报告摘要:  

Many estimation procedures used for causal inference rely on accurately measured data. However, in experimental and observational studies, measurement errors are widespread. When a binary treatment indicator subjects to measurement error (misclassification occurs), methods that involve error-free treatment indicators may instead lead to biased estimates. In this paper, we present three classes of estimators that are respectively consistent and asymptotically normal in three different models and, meanwhile, propose a multiply robust estimation of the average treatment effect based on a semiparametric theory framework, for settings with misclassified treatment. The proposed multiply robust estimation is consistent when either one of the three models holds and achieves the semiparametric efficiency bound as long as all the models are correct. We demonstrate the satisfactory performance of the proposed methods through simulation experiments and real data analysis.
