New method tackles causal effect estimation with bias and confounding

A new research paper introduces a regression-based method for estimating causal effects in complex scenarios involving both selection bias and confounding. The proposed Two-Step Regression (TSR) estimator, which can incorporate non-linear functions, leverages proxy variables to adjust for these distortions. The authors demonstrate that TSR is consistent with existing estimators when confounding is absent but offers lower variance, and simulations confirm its effectiveness in scenarios with both selection bias and confounding.
