Course Information
Description
Beginning with the randomized clinical trial as a paradigm, this course examines common problems in the design, analysis, and interpretation of observational studies. Cohort and case-control studies are the focus of the discussion, but not to the exclusion of other designs. Problems of exposure and disease definitions, time-dependent effects, confounding, and misclassification are considered in the light of data sources typically available. Relevant statistical methods are introduced but not developed in detail.
Course Prerequisites: EPI202 and (BIO200 or ID200 or BST201 or BST202&203 or BST206 or PHS 2000A). All prerequisites may be taken concurrently.
