A General Approach for Calibration Weighting under Missing at Random

Yonghyun Kwon, Jae Kwang Kim, Yumou Qiu

We propose a unified class of calibration weighting methods based on weighted generalized entropy to handle missing at random (MAR) data with improved stability and efficiency. The…

Collaborative Indirect Treatment Comparisons with Multiple Distributed Single-arm Trials

Yuru Zhu, Huiyuan Wang, Haitao Chu +2

When randomized controlled trials are impractical or unethical to simultaneously compare multiple treatments, indirect treatment comparisons using single-arm trials offer valuable…

Multiply Robust Inference of Average Treatment Effects by High-dimensional Empirical Likelihood

Xintao Xia, Yumou Qiu

In this paper, we develop a multiply robust inference procedure of the average treatment effect (ATE) for data with high-dimensional covariates. We consider the case where it is di…

Generalized entropy calibration for analyzing voluntary survey data

Yonghyun Kwon, Jae Kwang Kim, Yumou Qiu

Statistical analysis of voluntary survey data is an important area of research in survey sampling. We consider a unified approach to voluntary survey data analysis under the assump…
