Improving Treatment Effect Estimation in Trials through Adaptive Borrowing of External Controls
Qinwei Yang, Jingyi Li, Peng Wu +1
Randomized controlled trials (RCTs) often suffer from limited inferential efficiency in estimating treatment effects due to their small sample sizes. In recent years, incorporating…

Qinwei Yang, Jingyi Li, Peng Wu
Randomized controlled trials (RCTs) often exhibit limited inferential efficiency in estimating treatment effects due to small sample sizes. In recent years, the combination of exte…
Optimal Policy Adaptation under Covariate Shift
Xueqing Liu, Qinwei Yang, Zhaoqing Tian +2
Transfer learning of prediction models has been extensively studied, while the corresponding policy learning approaches are rarely discussed. In this paper, we propose principled a…
Identification and Estimation of Long-Term Treatment Effects with Monotone Missing
Qinwei Yang, Ruocheng Guo, Shasha Han +1
Estimating long-term treatment effects has a wide range of applications in various domains. A key feature in this context is that collecting long-term outcomes typically involves a…
