Round 1

Reviewer 1 Report

This article provides nice complementary numerical studies for the penalized spline of propensity for treatment comparisons (PENCOMP) compared with standard IPTW and AIPTW methods in misspecified models. My only concern is the following minor points.

1. line 81; (0,1) would be {0,1}
2. line 164; w_i should be W_i in the definition of Δ_AIPTW.
