Abstract :

Estimating the average causal effect of an exposure on an outcome is a common goal in many observational studies. One challenging issue is how to properly select and adjust for confounding factors, especially when sample size is small. In this talk, we present a Bayesian approach to identify and adjust for confounders in an automatic and data-driven way. Our work extends the Bayesian adjustment for confounding (BAC) method to the framework of generalized linear models, which allows for arbitrary types of exposure and outcome. Our method also allows for the inclusion and selection of interactions between exposure and confounders. In simulation studies, we compare our proposed method with propensity score-based methods.
