Department of Epidemiology and Biostatistics, University of Georgia, Athens, GA 30602, USA
Stat Med 31:2660-75. 2012..Numerical studies, including simulations and application to an HIV clinical trial, demonstrate the satisfactory finite-sample performance of the proposed approaches...
Supervised group Lasso with applications to microarray data analysisShuangge Ma
Department of Epidemiology and Public Health, Yale University, New Haven, CT 06520, USA
BMC Bioinformatics 8:60. 2007..However, most available statistical methods for gene selection do not take into consideration the cluster structure...
Evaluating markers for treatment selection based on survival timeXiao Song
Department of Epidemiology and Biostatistics, College of Public Health, University of Georgia, GA, U S A
Stat Med 30:2251-64. 2011..We show that the proposed estimators are consistent and asymptotically normal. The performance is assessed by simulation studies and illustrated through an application to data from a cancer clinical trial...
Multiple augmentation for interval-censored data with measurement errorXiao Song
Department of Epidemiology and Biostatistics, College of Public Health, University of Georgia, Athens, GA 30602, USA
Stat Med 27:3178-90. 2008..The proposed approach is easy to implement and can be readily extended to other semiparametric models. Extensive simulations show that the proposed approach has satisfactory finite-sample performance. The ACTG 175 data are then analyzed...

Department of Biostatistics, University of Washington, Seattle, WA 98195, USA
BMC Bioinformatics 7:253. 2006..It is also of interest to develop methods for evaluation of classification performance and ranking of identified biomarkers...
A semiparametric approach for the nonparametric transformation survival model with multiple covariatesXiao Song
Department of Biostatistics, University of Washington, Seattle, WA 98195, USA
Biostatistics 8:197-211. 2007..The estimator is evaluated via simulation studies and illustrated with the Veterans Administration lung cancer data set...
A corrected pseudo-score approach for additive hazards model with longitudinal covariates measured with errorXiao Song
Department of Biostatistics, University of Washington, 357232, Seattle, WA 98195 7232, USA
Lifetime Data Anal 12:97-110. 2006..The estimator has an explicit form and is shown to be consistent and asymptotically normal. We illustrate the method via simulations and by application to data from an HIV clinical trial...
