Nested Sensitivity Envelopes for Transported Quantile Treatment Effects
Pengyun Wang
We study target-population quantile treatment effects when a source study may have unmeasured treatment confounding and may not transport to a target population after conditioning…

Regularity, Phase Transitions, and Uniform Inference for Proximal Counterfactual Quantile Processes
Pengyun Wang
This paper develops semiparametric theory for counterfactual distribution, quantile, and lower-tail risk processes under unmeasured confounding using proximal negative-control prox…

Efficient Transported Distributional and Quantile Treatment Effects with Surrogate-Assisted Missing Primary Outcomes
Pengyun Wang
We study target-population distributional and quantile treatment effects when a source study observes treatment and post-treatment surrogates for all source units but observes a lo…
