Abstract:
|
An important goal in estimating the causal effect is to achieve balance in the covariates. In addition to estimating the average treatment effect or average treatment effect in the treated other quantities such as quantiles or the quantile treatment effect may be of interest. We propose a multiply robust method for estimating marginal quantiles of potential outcomes by achieving mean balance in (1) the propensity score, and (2) the conditional distributions of potential outcomes. An empirical likelihood or entropy measure can be utilized instead of using inverse probability weighting. Simulation studies are conducted across different scenarios of correctness in both the propensity score models and outcome models. Our estimator is consistent if any of the models are correctly specified.
