Doctoral course within the doctoral programme in Epidemiology
Course number: 2797
Credit points: 2
After successfully completing this course you as a student are expected to be able to:
- choose a suitable regression model for assessing a specific research hypothesis using data collected from an epidemiological study, fit the model using standard statistical software, evaluate the fit of the model, and interpret the results.
- explain the concept of confounding in epidemiological studies and demonstrate how to control/adjust for confounding using statistical models.
- apply and interpret appropriate statistical models for studying effect modification.
- critically evaluate the methodological aspects (design and analysis) of a scientific article reporting an epidemiological study.
Learning outcomes are classified according to Bloom's taxonomy: knowledge, comprehension, application, analysis, synthesis, and evaluation.
