Odum Institute: Using DAGs as Tools for Variable Selection

Gettin’ daggity with it: Using DAGs as Tools for Variable Selection

Ever pondered whether to include a variable in an analysis – is the variable necessary, will its inclusion/exclusion introduce bias in the analysis? Why is the variable important anyways – is it a mediator, a moderator, a confounder some combination of these???

This course introduces how to incorporate DAGs (Directed Acyclic Graphs) in analysis planning to help think through what variables to collect and use (or refrain from using) in an analysis.
