Course Instructors:

Third offering in the Epidemiologic Methods sequence. Expands on the presentation of modern epidemiologic inference emphasizing the theory and practice of epidemiologic data analysis. Covers, in detail, detection and analysis of confounding and effect modification using multivariable models in the context of the major epidemiological study designs. Develops an understanding of the underlying principles & assumptions, practical application, and correct interpretation of the epidemiologic results using appropriate multivariable models. Provides experience through laboratory exercises with applying epidemiologic analysis in both infectious and non-infectious disease settings.

Learning Objective(s):
Upon successfully completing this course, students will be able to:
Link appropriate analytic models with public health research questions and epidemiologic study designs
Conduct and interpret epidemiologic analyses from a range of multivariable models (including linear, logistic, and Cox regression models)
Account for the presence of confounding bias using both stratified approaches and multivariable regression
Identify and critically evaluate different approaches to modeling complex exposures including dose-response relationships & time-varying exposures
Analyze data for the presence of effect modification
Critically discuss model limitations with respect to: misspecification, outliers and residual bias
