Probabilistic Clustering using Shared Latent Variable Model for Assessing Alzheimers Disease Biomarkers
Yizhen Xu, Scott Zeger, Zheyu Wang
The preclinical stage of many neurodegenerative diseases can span decades before symptoms become apparent. Understanding the sequence of preclinical biomarker changes provides a cr…
Causal Inference using Multivariate Generalized Linear Mixed-Effects Models with Longitudinal Data
Yizhen Xu, Jisoo Kim, Laura K. Hummers +2
Dynamic prediction of causal effects under different treatment regimes conditional on an individual's characteristics and longitudinal history is an essential problem in precision…
An Efficient Approach for Optimizing the Cost-effective Individualized Treatment Rule Using Conditional Random Forest
Yizhe Xu, Tom H. Greene, Adam P. Bress +7
Evidence from observational studies has become increasingly important for supporting healthcare policy making via cost-effectiveness (CE) analyses. Similar as in comparative effect…
Calibration Error for Heterogeneous Treatment Effects
Yizhe Xu, Steve Yadlowsky
Recently, many researchers have advanced data-driven methods for modeling heterogeneous treatment effects (HTEs). Even still, estimation of HTEs is a difficult task -- these method…
