Abstract

Estimating causal treatment effect in longitudinal, observational data can be complex due to the need to control for selection bias in the full history of covariates used in the treatment assignment. Having a robust approach to deal with the lack of randomization between treatment groups is critical because the history of covariates used in the treatment assignment grows rapidly with the length of the observation period.

We present regression estimators that can compare longitudinal treatments ...
