Propensity score weighted Cox regression for survival outcomes in observational studies with multiple or factorial treatments
Zixian Zhao, Chengxin Yang, Fan Li
In observational studies with survival or time-to-event outcomes, a propensity score weighted marginal Cox proportional hazard model with the treatment variable as the only predict…
On the permutation equivariance principle for causal estimands
Jiaqi Tong, Fan Li
In many causal inference problems, multiple action variables, such as factors, mediators, or network units, often share a common causal role yet lack a natural ordering. To avoid a…
A Bayesian nonparametric approach to mediation and spillover effects with multiple mediators in cluster-randomized trials
Yuki Ohnishi, Fan Li
Cluster randomized trials (CRTs) with multiple unstructured mediators present significant methodological challenges for causal inference due to within-cluster correlation, interfer…
Subgroup Balancing Propensity Score
Jing Dong, Junni L Zhang, Fan Li
We investigate the estimation of subgroup treatment effects with observational data. Existing propensity score matching and weighting methods are mostly developed for estimating ov…
