Re: “addressing extreme propensity scores via the overlap weights”

In the article “Addressing Extreme Propensity Scores via the Overlap Weights” by Li et al. (1), the asymmetric propensity score (PS) trimming of St ürmer et al. (2) was incorrectly implemented as a comparative approach in the simulation study. This incorrect implementation led to large bias for estimating the average treatment effect. In this erratum, we provide corrected simulation results for asymmetric PS trimming.
