The world has changed for empirical social scientists. The new types of “big data” have generated an entire new research field—that of data science. That world is dominated by computer scientists who have generated new ways of creating and collecting data, developed new analytical and statistical techniques, and provided new ways of visualizing and presenting information. These new sources of data and techniques have the potential to transform the way applied social science is done. Research has certainly changed. Researchers draw on data that are “found” rather than “made” by federal agencies; those publishing in leading academic journals are much less likely today to draw on preprocessed survey data. And the jobs have changed. The new job title of “data scientist” is highlighted in job advertisements on CareerBuilder.com and Burning-glass.com—in the same category as statisticians, economists, and other quantitative social scientists if starting salaries are useful indicators.
The goal of this course is to provide social scientists with an understanding of the key elements of this new science, its value, and the opportunities for doing better work. The goal is also to identify the many ways in which the analytical toolkits possessed by social scientists can be brought to bear to enhance the generalizability of the work done by computer scientists.
We meet four-five times for an extended period of time in this seminar. In the first sessions we will introduce new data sources and tools to tackle them. We will also discuss extensively what research questions can be answered with which data source. In the month following we expect participants to engage in their own data collection and present and critically discuss their results in the following meetings. We advise all students to set aside time in those weeks, to fully work on the assigned projects.
We will use the following books and require familiarity with the books in preparation for the course.

Course Description: This course provides an introduction to supervised statistical learning techniques such as decision trees, random forests and boosting and discusses their potential application in the social sciences. These methods focus on predicting an outcome Y based on some data-driven function f(X) and therefore facilitate new research perspectives in comparison with traditional regression models, which primarily focus on causation. Predictive methods also provide a valuable extension to the empirical social scientists' toolkit as new data sources become more prominent. The discussed methods will be implemented using the statistical programming language R.

Knowledge of regression analysis
Multilevel modeling is used when observations on the individual level are nested in units of one or more higher levels (e.g. students in classes in schools). The course will cover the logic of multilevel modeling, its statistical background, and implementation with Stata. Applications will come from international comparative research treating countries as the higher level units. Data from the International Social Survey Program and the PIONEUR project (on intra-European migration) serve as examples. However, students are also encouraged to bring their own data.

This seminar will provide an introduction how to use R, a powerful programming language that is often used for statistical analyses, simulations, and cognitive modeling. The seminar first will provide a thorough introduction covering the core functionality such as objects, functions, data management, and plotting. The last sessions of the seminar will address how to perform specific statistical analyses in R such as: * Generalized linear mixed models with lme4 (also known as hierarchical models) * Simple structural equation models * Basic set-up of Monte-Carlo simulations * Simple cognitive modeling (e.g., signal detection or multinomial processing trees) It is planned that participants practice R in homework assignments and work on small group projects such as analyzing own data, replicating a paper, or running a small simulation.

This course offers an introduction to the Python programming language with a focus on solving social science problems. The course is structured around a series of practical exercises for working with basic Python functionalities, reading structured and “unstructured” datasets into Python, using statistical and network analytic methods and designing visualizations. The course demonstrates the utility of working with Python in two ways. We are going to replicate quantitative analyses from publications in social science journals and we will take advantage of Python’s compatibility with application programming interfaces (APIs) in order to explore several new data sources (e.g., Twitter, Wikipedia, Meetup, Github, Discogs). The replication exercises require some mandatory reading and supplementary materials will be suggested. The main focus of the course will concentrate on practicing Python programming and discussing when and how it might benefit social science research. We will also take time to discuss the applicability of Python to ongoing research interests among the participants. No prior programming experience is required.

All statistical models are false. Instead of searching for the “best” or the “true” model specification, the logic of robustness testing is to accept model uncertainty and to study how model estimates and inferences react to changes in model assumptions. After looking at classical contributions (Leamer, Rosenbaum, Manski, and Frank), we will discuss in greater detail the new robustness framework proposed by Neumayer and Plümper. This covers robustness testing problems of measurement uncertainty, omitted variables, functional form, causal and temporal heterogeneity, dynamics and spatial dependence. This course will rely heavily on students’ presentations of specific robustness tests.

The first law of geography states that “everything is related to everything else, but near things are more related than distant things” (Tobler 1970: 236). In the Social Sciences, geographic data and spatial analyses offer rich insights into a variety of relevant research questions (Franzese and Hays 2008). The course covers crucial concepts involved in spatial analysis, introduces a toolbox of statistical models and pays particular attention to the accessible implementation of spatial analysis in free software (working with R and packages for spatial analysis). This implies that participants should bring their Laptop with R (required) and RStudio (recommended) installed.
Parts
I. Concepts
The first part of the course deals with the concepts involved in spatial analysis. We will spend some time getting to know “W”, the connectivity matrix which defines spatial dependencies (Neumayer and Plümper 2016). Alternative conceptions of neighborhood and the weighting of connections are discussed. For example, spatial proximity does not necessarily imply geographic proximity, as for instance trade or information exchange can bring distance things closely together. Further concepts handled include the geo-referencing of data, regarding both its use and generation.
II. Models
To test hypotheses based on spatial data, tailored statistical tools are needed. The second part of the course is dedicated to spatial correlation coefficients (such as Moran’s I), varieties of spatial regression models (variants of spatial lags; categorical, count and duration specifications), spatio-temporal models as well as extensions to the multilevel case. The options offered by a Bayesian approach to spatial data analysis are also discussed.
III. Implementation
As mentioned, one focus of the course is the accessible implementation of spatial analysis. To this end, the free statistical software R is used (https://www.r-project.org/). Its advantages in addition to the open source character are the provision of user-written packages, including several on geodata and spatial analysis (such as sp, maptools or spdep) as well as powerful graphical capabilities (see Bivand et al. 2013). Recommended is the combination of R with the RStudio editor/
IV. Applications
The last part of the course is devoted to the participants’ own applications in the field of geographic data and spatial analysis. Anticipated throughout the course, they will look for and handle their own geographic data and we will jointly identify adequate spatial models to test hypotheses. The final meeting is dedicated to the presentation and discussion of the paper outlines, with a focus on a (preliminary) spatial analysis of geographic data.
Assessment
Active participation, exercises, presentation with preliminary analysis, paper on spatial analysis of geographic data (4000-5000 words)

Survey experiments are an increasingly popular tool in the social sciences. The attractiveness of this hybrid methodology stems from the fact that it combines the internal validity of experimental research with the external validity of survey sampling. After a brief review of the key concepts and benefits of these two foundations, the course will discuss both the design and the analysis of modern survey experiments. In particular, we will take an in-depth look into the design and analysis of factorial surveys/

Knowledge of Multivariate Analysis
This course serves as an introduction to a multitude of probability models that are appropriate when the linear model is inadequate. After introducing the fundamentals from which statistical models are developed, this course will focus on one specific theory of inference, namely on the statistical theory of maximum likelihood. We will also devote considerable time to statistical programming, simulating and conveying quantities of material interest of such models (using R).
Course Readings:
Students who wish to pass this course must complete homework assignments and produce a research paper. Participation in the tutorial session (2 ECTS) is necessary for the assignments which complement the lecture (6 ECTS).
Tutorial
This tutorial accompanies the course “Multivariate Analyses” in the M.A. program in Political Science. The lab sessions will focus on the practical issues associated with quantitative methods, including obtaining and preparing data sets, how to use statistical software, which tests to use for different kinds of problems, how to graph data effectively for presentation and analysis, and how to interpret results. The seminar will also serve as a software tutorial. No prior knowledge of statistical programming is expected.
The goal of this course is to provide an introduction into maximum-likelihood estimation.

This course aims at fostering the interdisciplinary spirit of the graduate students at the GESS. Participants will attend and participate at the GESS Research Day and the Science Speed Dating event in order to discover their potential for interdisciplinary and collaborative work. Participation at the GESS Research Day will include presenting an on-going working paper, discuss a presentation from another field of study and write a referee report about it and participate in one discussion panel. The idea of the discussion panels is to bring together students from different centers with matching research interests. Within these panels, the students should talk about their research interests and ideally come up with some joint interdisciplinary research ideas.
During the Science Speed Dating event, course participants will discuss with graduate students from other departments and develop at least one collaborative research proposal. The proposal will be presented in a third meeting around one month after the speed dating.
Assessment:
If you are interested please register until January 31st, 2018, by sending a title and an extended abstract of your research project you would like to present to your respective center representative. Please indicate in your e-mail your fields of interest and if you have any, mention fields you would like to collaborate with.

Knowledge of Stata is helpful but not required.
The number of foreign-born persons in Western Europe increased dramatically over the past three decades. Also in Eastern European countries, immigrants, particularly refugees, are increasing in numbers for the first time in recent history. This produces many social outcomes that link to trust, voting, inequality and the role of the state. For example, having more foreigners in a country or region may reduce trust and increase intergroup conflicts. In Germany, for the first time since WWII, an anti-immigrant, populist party gained substantial political power. Also, many immigrants, in particular refugees or family reunification immigrants, face substantial labor market disadvantage and poverty. Many states were not equipped to deal with immigration and refugee asylum seeking on the scale that developed in recent history. All of these features of European societies affect public preferences and public opinion. At the same time, public preferences and opinion shapes how governments react to immigration.
This course considers the many linkages between public preferences and social policies as they relate to immigrants, immigration and refugee seeking. It considers how the public reacts to immigration in voting, group dynamics and social movements (protests, violence). It considers how immigrants react to their statuses in European countries. It looks at how public reactions link to state policies and the distribution of power among political parties, and how states interact with each other in the European Union. All of this will take place with a focus on survey data. We will read relevant literature and analyze relevant data as part of the course work. This data analysis will take place using Stata statistical software.

Course Description: This course provides an introduction to supervised statistical learning techniques such as decision trees, random forests and boosting and discusses their potential application in the social sciences. These methods focus on predicting an outcome Y based on some data-driven function f(X) and therefore facilitate new research perspectives in comparison with traditional regression models, which primarily focus on causation. Predictive methods also provide a valuable extension to the empirical social scientists' toolkit as new data sources become more prominent. The discussed methods will be implemented using the statistical programming language R.

Knowledge of regression analysis
Multilevel modeling is used when observations on the individual level are nested in units of one or more higher levels (e.g. students in classes in schools). The course will cover the logic of multilevel modeling, its statistical background, and implementation with Stata. Applications will come from international comparative research treating countries as the higher level units. Data from the International Social Survey Program and the PIONEUR project (on intra-European migration) serve as examples. However, students are also encouraged to bring their own data.

This seminar will provide an introduction how to use R, a powerful programming language that is often used for statistical analyses, simulations, and cognitive modeling. The seminar first will provide a thorough introduction covering the core functionality such as objects, functions, data management, and plotting. The last sessions of the seminar will address how to perform specific statistical analyses in R such as: * Generalized linear mixed models with lme4 (also known as hierarchical models) * Simple structural equation models * Basic set-up of Monte-Carlo simulations * Simple cognitive modeling (e.g., signal detection or multinomial processing trees) It is planned that participants practice R in homework assignments and work on small group projects such as analyzing own data, replicating a paper, or running a small simulation.

This course offers an introduction to the Python programming language with a focus on solving social science problems. The course is structured around a series of practical exercises for working with basic Python functionalities, reading structured and “unstructured” datasets into Python, using statistical and network analytic methods and designing visualizations. The course demonstrates the utility of working with Python in two ways. We are going to replicate quantitative analyses from publications in social science journals and we will take advantage of Python’s compatibility with application programming interfaces (APIs) in order to explore several new data sources (e.g., Twitter, Wikipedia, Meetup, Github, Discogs). The replication exercises require some mandatory reading and supplementary materials will be suggested. The main focus of the course will concentrate on practicing Python programming and discussing when and how it might benefit social science research. We will also take time to discuss the applicability of Python to ongoing research interests among the participants. No prior programming experience is required.

All statistical models are false. Instead of searching for the “best” or the “true” model specification, the logic of robustness testing is to accept model uncertainty and to study how model estimates and inferences react to changes in model assumptions. After looking at classical contributions (Leamer, Rosenbaum, Manski, and Frank), we will discuss in greater detail the new robustness framework proposed by Neumayer and Plümper. This covers robustness testing problems of measurement uncertainty, omitted variables, functional form, causal and temporal heterogeneity, dynamics and spatial dependence. This course will rely heavily on students’ presentations of specific robustness tests.

The first law of geography states that “everything is related to everything else, but near things are more related than distant things” (Tobler 1970: 236). In the Social Sciences, geographic data and spatial analyses offer rich insights into a variety of relevant research questions (Franzese and Hays 2008). The course covers crucial concepts involved in spatial analysis, introduces a toolbox of statistical models and pays particular attention to the accessible implementation of spatial analysis in free software (working with R and packages for spatial analysis). This implies that participants should bring their Laptop with R (required) and RStudio (recommended) installed.
Parts
I. Concepts
The first part of the course deals with the concepts involved in spatial analysis. We will spend some time getting to know “W”, the connectivity matrix which defines spatial dependencies (Neumayer and Plümper 2016). Alternative conceptions of neighborhood and the weighting of connections are discussed. For example, spatial proximity does not necessarily imply geographic proximity, as for instance trade or information exchange can bring distance things closely together. Further concepts handled include the geo-referencing of data, regarding both its use and generation.
II. Models
To test hypotheses based on spatial data, tailored statistical tools are needed. The second part of the course is dedicated to spatial correlation coefficients (such as Moran’s I), varieties of spatial regression models (variants of spatial lags; categorical, count and duration specifications), spatio-temporal models as well as extensions to the multilevel case. The options offered by a Bayesian approach to spatial data analysis are also discussed.
III. Implementation
As mentioned, one focus of the course is the accessible implementation of spatial analysis. To this end, the free statistical software R is used (https://www.r-project.org/). Its advantages in addition to the open source character are the provision of user-written packages, including several on geodata and spatial analysis (such as sp, maptools or spdep) as well as powerful graphical capabilities (see Bivand et al. 2013). Recommended is the combination of R with the RStudio editor/
IV. Applications
The last part of the course is devoted to the participants’ own applications in the field of geographic data and spatial analysis. Anticipated throughout the course, they will look for and handle their own geographic data and we will jointly identify adequate spatial models to test hypotheses. The final meeting is dedicated to the presentation and discussion of the paper outlines, with a focus on a (preliminary) spatial analysis of geographic data.
Assessment
Active participation, exercises, presentation with preliminary analysis, paper on spatial analysis of geographic data (4000-5000 words)

Survey experiments are an increasingly popular tool in the social sciences. The attractiveness of this hybrid methodology stems from the fact that it combines the internal validity of experimental research with the external validity of survey sampling. After a brief review of the key concepts and benefits of these two foundations, the course will discuss both the design and the analysis of modern survey experiments. In particular, we will take an in-depth look into the design and analysis of factorial surveys/

Knowledge of Multivariate Analysis
This course serves as an introduction to a multitude of probability models that are appropriate when the linear model is inadequate. After introducing the fundamentals from which statistical models are developed, this course will focus on one specific theory of inference, namely on the statistical theory of maximum likelihood. We will also devote considerable time to statistical programming, simulating and conveying quantities of material interest of such models (using R).
Course Readings:
Students who wish to pass this course must complete homework assignments and produce a research paper. Participation in the tutorial session (2 ECTS) is necessary for the assignments which complement the lecture (6 ECTS).
Tutorial
This tutorial accompanies the course “Multivariate Analyses” in the M.A. program in Political Science. The lab sessions will focus on the practical issues associated with quantitative methods, including obtaining and preparing data sets, how to use statistical software, which tests to use for different kinds of problems, how to graph data effectively for presentation and analysis, and how to interpret results. The seminar will also serve as a software tutorial. No prior knowledge of statistical programming is expected.
The goal of this course is to provide an introduction into maximum-likelihood estimation.

The idea of deliberative democracy is the most influential and controversial normative conception of modern democratic theory. According to this model, deliberative communication is at the heart of a truly democratic political process. It involves carefully examining political problems and arriving at well-reasoned solutions after dialogical, inclusive and respectful consideration of diverse points of view. In various ways, deliberative communication is believed to enhance the quality of democracy. Ordinary people’s everyday communication about political matters is often seen as the foundation of a truly deliberative democracy. But can ordinary citizens’ meet the high standards of deliberative communication? To what extent does their communication correspond to the deliberative ideal, and which consequences follow from this? Especially in times of increasing party-political and ideological polarization, spurred by the rise of right-wing populism, these are important questions. The seminar offers a unique opportunity to get first-hand insights on whether citizens can and do deliberate. Following a discussion of the concept of democratic deliberation and its measurement participants will analyze freshly collected data from an extensive survey on citizens’ (offline and online) everyday communication conducted in an MZES project. It will be explored how citizens discuss politics, which factors promote a more or less deliberative style of everyday communication, and which consequences this has for citizens’ political attitudes and behaviors.

This course aims at fostering the interdisciplinary spirit of the graduate students at the GESS. Participants will attend and participate at the GESS Research Day and the Science Speed Dating event in order to discover their potential for interdisciplinary and collaborative work. Participation at the GESS Research Day will include presenting an on-going working paper, discuss a presentation from another field of study and write a referee report about it and participate in one discussion panel. The idea of the discussion panels is to bring together students from different centers with matching research interests. Within these panels, the students should talk about their research interests and ideally come up with some joint interdisciplinary research ideas.
During the Science Speed Dating event, course participants will discuss with graduate students from other departments and develop at least one collaborative research proposal. The proposal will be presented in a third meeting around one month after the speed dating.
Assessment:
If you are interested please register until January 31st, 2018, by sending a title and an extended abstract of your research project you would like to present to your respective center representative. Please indicate in your e-mail your fields of interest and if you have any, mention fields you would like to collaborate with.
Course dates:
- Research Day: March 5th, 2018
- Speed Dating: May 15th, 2018
- Presentation of research proposal: tbd, around mid-June
CSSR, Literature Review
The goal of this course is to provide support and crucial feedback on writing students' dissertation proposal. Such a proposal is a research outline that delineates the doctoral thesis project, including the motivation for research question(s), the survey of the relevant theoretical and empirical contributions, the development of a theoretical framework, the specification of the methodology and planned empirical analysis.
You should be prepared to address the following questions: What makes that an interesting question? Is it an important question? What contributions would this question and the answers make to the scholarly literature? What strategies are there to answer your research question(s)?

The world has changed for empirical social scientists. The new types of “big data” have generated an entire new research field—that of data science. That world is dominated by computer scientists who have generated new ways of creating and collecting data, developed new analytical and statistical techniques, and provided new ways of visualizing and presenting information. These new sources of data and techniques have the potential to transform the way applied social science is done. Research has certainly changed. Researchers draw on data that are “found” rather than “made” by federal agencies; those publishing in leading academic journals are much less likely today to draw on preprocessed survey data. And the jobs have changed. The new job title of “data scientist” is highlighted in job advertisements on CareerBuilder.com and Burning-glass.com—in the same category as statisticians, economists, and other quantitative social scientists if starting salaries are useful indicators.
The goal of this course is to provide social scientists with an understanding of the key elements of this new science, its value, and the opportunities for doing better work. The goal is also to identify the many ways in which the analytical toolkits possessed by social scientists can be brought to bear to enhance the generalizability of the work done by computer scientists.
We meet four-five times for an extended period of time in this seminar. In the first sessions we will introduce new data sources and tools to tackle them. We will also discuss extensively what research questions can be answered with which data source. In the month following we expect participants to engage in their own data collection and present and critically discuss their results in the following meetings. We advise all students to set aside time in those weeks, to fully work on the assigned projects.
We will use the following books and require familiarity with the books in preparation for the course.

This course continues where last semester’s course Introduction to Bayesian Statistics for Social Scientists I left off. But newcomers are welcome. We will extend our Bayesian tool kit by adding Bayesian models of ordered and un-ordered categorical outcomes, Bayesian measurement models, and Bayesian Non-parametric methods. We will also spend some time to further discuss Prior specifications and issues of Bayesian model checking, selection and averaging.

Survey experiments are an increasingly popular tool in the social sciences. The attractiveness of this hybrid methodology stems from the fact that it combines the internal validity of experimental research with the external validity of survey sampling. After a brief review of the key concepts and benefits of these two foundations, the course will discuss both the design and the analysis of modern survey experiments. In particular, we will take an in-depth look into the design and analysis of factorial surveys/

Knowledge of Multivariate Analysis
This course serves as an introduction to a multitude of probability models that are appropriate when the linear model is inadequate. After introducing the fundamentals from which statistical models are developed, this course will focus on one specific theory of inference, namely on the statistical theory of maximum likelihood. We will also devote considerable time to statistical programming, simulating and conveying quantities of material interest of such models (using R).
Course Readings:
Students who wish to pass this course must complete homework assignments and produce a research paper. Participation in the tutorial session (2 ECTS) is necessary for the assignments which complement the lecture (6 ECTS).
Tutorial
This tutorial accompanies the course “Multivariate Analyses” in the M.A. program in Political Science. The lab sessions will focus on the practical issues associated with quantitative methods, including obtaining and preparing data sets, how to use statistical software, which tests to use for different kinds of problems, how to graph data effectively for presentation and analysis, and how to interpret results. The seminar will also serve as a software tutorial. No prior knowledge of statistical programming is expected.
The goal of this course is to provide an introduction into maximum-likelihood estimation.

This course aims at fostering the interdisciplinary spirit of the graduate students at the GESS. Participants will attend and participate at the GESS Research Day and the Science Speed Dating event in order to discover their potential for interdisciplinary and collaborative work. Participation at the GESS Research Day will include presenting an on-going working paper, discuss a presentation from another field of study and write a referee report about it and participate in one discussion panel. The idea of the discussion panels is to bring together students from different centers with matching research interests. Within these panels, the students should talk about their research interests and ideally come up with some joint interdisciplinary research ideas.
During the Science Speed Dating event, course participants will discuss with graduate students from other departments and develop at least one collaborative research proposal. The proposal will be presented in a third meeting around one month after the speed dating.
Assessment:
If you are interested please register until January 31st, 2018, by sending a title and an extended abstract of your research project you would like to present to your respective center representative. Please indicate in your e-mail your fields of interest and if you have any, mention fields you would like to collaborate with.
Course dates:
- Research Day: March 5th, 2018
- Speed Dating: May 15th, 2018
- Presentation of research proposal: tbd, around mid-June
