Asymptotics of Nonparametric Estimation under General Non-monotone MAR Missingness: A Nonparametric Maximum Likelihood Approach
Yating Zou, Huimin Hu, Jeffrey Näf
Missing data constitute a pervasive challenge in empirical research. Consequently, there is an ever-growing number of methods designed to address this challenge, with multiple impu…
The Fidelity and Feedback Traps: The Case for Health Digital Twins as Modular Evolving Causal Systems
Nikki L. B. Freeman, Yating Zou, Kyungbok Lee +3
The paper examines pitfalls of using digital twins in healthcare, such as over‑reliance on model accuracy (fidelity trap) and biased updates from self‑generated data (feedback trap…
Distributional Random Forests for Complex Survey Designs
Yating Zou, Marcos Matabuena, Michael R. Kosorok
We study estimation of the conditional law and continuous measurable maps of it when takes values in a locally compact Polish space (e.g., $\mathbb…
Latent Utility Q-Learning for Preference-Adaptive Dynamic Treatment Regimes
Joshua P. Zitovsky, Yating Zou, Leslie Wilson +1
Optimizing individualized treatment sequences for patients who weigh multiple, competing outcomes differently poses a challenge for dynamic treatment regime (DTR) methods, which ty…
