A Unified Three-State Model Framework for Analysis of Treatment Crossover in Survival Trials
Zile Zhao, Ye Li, Xiaodong Luo +1
We present a unified three-state model (TSM) framework for evaluating treatment effects in clinical trials in the presence of treatment crossover. Researchers have proposed diverse…
Generative Quantile Regression with Variability Penalty
Shijie Wang, Minsuk Shin, Ray Bai
Quantile regression and conditional density estimation can reveal structure that is missed by mean regression, such as multimodality and skewness. In this paper, we introduce a dee…
Two-Step Mixed-Type Multivariate Bayesian Sparse Variable Selection with Shrinkage Priors
Shao-Hsuan Wang, Ray Bai, Hsin-Hsiung Huang
We introduce a Bayesian framework for mixed-type multivariate regression using continuous shrinkage priors. Our framework enables joint analysis of mixed continuous and discrete ou…
A Bayesian Selection Model for Correcting Outcome Reporting Bias With Application to a Meta-analysis on Heart Failure Interventions
Ray Bai, Xiaokang Liu, Lifeng Lin +4
Multivariate meta-analysis (MMA) is a powerful tool for jointly estimating multiple outcomes' treatment effects. However, the validity of results from MMA is potentially compromise…
Quantifying patient and neighborhood risks for stillbirth and preterm birth in Philadelphia with a Bayesian spatial model
Cecilia Balocchi, Ray Bai, Jessica Liu +4
Stillbirth and preterm birth are major public health challenges. Using a Bayesian spatial model, we quantified patient-specific and neighborhood risks of stillbirth and preterm bir…
Spike-and-Slab Meets LASSO: A Review of the Spike-and-Slab LASSO
Ray Bai, Veronika Rockova, Edward I. George
High-dimensional data sets have become ubiquitous in the past few decades, often with many more covariates than observations. In the frequentist setting, penalized likelihood metho…
