Section outline

  • Lecture: Interaction/Effect Modification

    Faculty: June Chan 

    BEFORE class on Feb. 11, 2021, please do the readings and view/review Parts 1-4 of Interaction/Effect Modification (listed on Feb. 11). You are responsible for the material in all parts, however note that Parts 1, 2a, and 2b may be more of a “review” for some. In particular, parts 2a and 2b may have been recently covered by Dr. Shiboski in BIO208. For these sections, you may wish to skim the slides, to ensure that you are familiar with the material but may opt not to watch the video lectures. Part 3 is a slide deck of definitions only (no video), and we will review some of this during the live lecture on 2/11. In the live lecture on 2/11, we will also be focusing on discussing interaction using the counterfactual framework.
