EPI271 Propensity Score Analysis: Theoretical & Practical Considerations - This course introduces basic and advanced theory underlying propensity score analyses and provides practical insights into the conduct of studies employing the method. Lectures are complemented by computer lab sessions devoted to the mechanics of estimating and using the propensity score as a tool to control for confounding in observational research. A course project involves the application of propensity scores to a data set. The course is offered during one week (morning lecturs and labs) in the Winter Session and open to all students with knowledge in multivariable methods to control for confounding (Instructors: Dr. Kurth, Dr. Seeger).
