Webdoing a bootstrap bias correction to the inverse probability weighting estimator (BBC-IPS), which has misspecified the PS score weights. The misspecifications of the PS score weights will induce bias in the estimation of the ATE. Kim and Yixiao (2016) have shown that the bootstrap bias correction for maximum likelihood WebNCV provides almost unbiased estimates of performance, while BBC-CV is more conservative with a difference in the bias of 0.013 points of accuracy on average. BBCD-CV is on par with NCV from ...
