Variable Selection for Propensity Score Models When Estimating Treatment Effects on Multiple Outcomes: a Simulation Study
PURPOSE: It is often preferable to simplify the estimation of treatment effects on multiple outcomes by using a single propensity score (PS) model. Variable selection in PS models impacts the efficiency and validity of treatment effects. However, the impact of different variable selection strategies...
