Causal Inference Methods Skill

Apply advanced econometric and statistical methods for causal identification in observational data.

Overview

The Causal Inference Methods skill enables application of propensity score methods, instrumental variables, difference-in-differences, regression discontinuity designs, and other quasi-experimental approaches for causal identification in observational social science data.
