    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.

    • Required Reading:

    Quantitative Bias Analysis (QBA) 

    The focus of this workshop is methods for conducting quantitative bias analysis in epidemiologic research. We will first provide a brief introduction to confounding, information bias, and selection bias using causal diagrams. Next, we will discuss deterministic and probabilistic bias analysis. Dr. Mayeda will discuss examples of specific biases in her own work on determinants of cognitive decline in older adults. At the end of the workshop, participants should walk away with an understanding of the motivations behind quantitative bias analysis and how to use tools for conducting quantitative bias analysis.

    The first two hours will contain the material for which students in EPI207 are responsible; the last hour is optional for the class.
