Design. To investigate the asymptotic biases described in Section 4 and also the finite‐sample performance of Δ ^ IPW 1 ∗, Δ ^ IPW 2 ∗, and Δ ^ AIPW ∗ under model misspecification, we perform three simulation studies with three different designs A–C. The first part of the simulations evaluates the finite‐sample performance of the estimators …
