Instrumental Variable Analysis in Underrepresented Subpopulations Powered by Knowledge Transfer
Ruoyu Wang, Zijian Xu, Zijian Guo +3
Instrumental variable (IV) analysis in underrepresented target populations suffers from low statistical efficiency and weak IV bias due to limited sample size. Leveraging external…
Semiparametric Mediation Analysis with Separately Observed Mediator and Outcome under Unmeasured Confounding
Sijia Li, Ruoyu Wang
Mediation analysis is widely used to disentangle causal pathways, yet in many real-world studies the mediator M and outcome Y are never jointly observed. This incompleteness breaks…
Debiased Estimating Equation Method for Robust and Efficient Mendelian Randomization Using a Large Number of Correlated Weak and Invalid Instruments
Ruoyu Wang, Haoyu Zhang, Xihong Lin
Mendelian randomization (MR) is a widely used tool for causal inference in the presence of unmeasured confounders, which uses single nucleotide polymorphisms (SNPs) as instrumental…
Adaptive and Efficient Learning with Blockwise Missing and Semi-Supervised Data
Yiming Li, Ruoyu Wang, Ying Wei +1
Data fusion enables powerful and generalizable analyses across multiple sources. However, different data collection capacities across different sources lead to blockwise missingnes…
