Ryan T. Moore is Associate Professor of Government at American University and Senior Social Scientist at The Lab @ DC. Ryan’s research interests center around statistical political methodology, with applications in American social policy. He develops and implements methods for political experiments, ecological data, missing data, causal inference, and geolocated data. Among his publications are twelve peer-reviewed journal articles, a book chapter, and four software packages and applications. His work has appeared in Political Analysis, The Lancet, and the Journal of Policy Analysis and Management, among other outlets. Ryan received his Ph.D. in government and social policy from Harvard University. While pursuing his Ph.D., he earned an A.M. in statistics. His B.A. is from Yale University in political science and mathematics.

Course Content
Do campaign messages actually affect public opinion? Does a refugee’s religion affect support for her asylum application? Do legislators respond when made aware of district preferences? This course develops a framework and a set of tools centered around answering causal questions such as these.

We lay foundations in the potential outcomes model, allowing us to identify causal inferences. We discuss why we might conduct field, survey, and laboratory experiments, best practices for designing and registering experiments, how to overcome common problems, and how to analyze experimental data.

We will touch on special topics such as interference and mediation, as well as methods for causal inference from observational data, such as matching, instruments, and discontinuity designs

Course Objectives
Students will gain understanding of the potential outcomes model, and how and why we often register and conduct experiments for causal inference. Students apply this understanding to experimental design, and will analyze experimental and observational data with attention to causal questions. Throughout, students will learn application through the R statistical language.

Course prerequisites
Students should have encountered conventional topics in introductory statistics, such as null hypothesis significance tests, confidence intervals, and linear regression. We will reintroduce such topics as needed.

Students should have some familiarity processing data with R or Stata.
