Empirical stratification for predictive treatment effect heterogeneity with post-treatment variables
Chao Cheng, Rui Wang, Yichi Zhang
Post-treatment variables (PVs), such as intercurrent events, treatment noncompliance, and behavioral responses to treatment, provide information about individuals' post-treatment r…
Separate versus pooled winsorization for group mean contrasts: a finite-sample theory
Chao Cheng, Chenshan Hu, Yukai Huang
Comparing group means is foundational to many statistical areas, including two-sample studies, randomized trials, and difference-in-differences designs, yet heavy-tailed outcomes c…
Nonparametric efficient inference for network quantile causal effects under partial interference
Chao Cheng, Fan Li
Interference arises when the treatment assigned to one individual affects the outcomes of other individuals. Commonly, individuals are naturally grouped into clusters, and interfer…
Causal mediation in cluster-randomized trials with multiple mediators: spillover-aware decomposition, identification, and semiparametric efficient inference
Jiaqi Tong, Chao Cheng, Fan Li
Causal mediation analysis in cluster-randomized trials (CRTs) is complicated by the presence of multiple mediators, intracluster correlation, and within-cluster interference. Exist…
