A semiparametric two-sample homogeneity test with nonignorable nonresponse using callback data
Xinyu Wang, Tao Yu, Chunlin Wang +1
Testing the homogeneity of two distributions is fundamental in statistics, but classical procedures may fail under nonignorable nonresponse. In many surveys, callback data record r…
Semiparametric inference for inequality measures under nonignorable nonresponse using callback data
Xinyu Wang, Chunlin Wang, Tao Yu +1
This paper develops semiparametric methods for estimation and inference of widely used inequality measures when survey data are subject to nonignorable nonresponse, a challenging s…
Maximum smoothed likelihood method for the combination of multiple diagnostic tests, with application to the ROC estimation
Fangyong Zheng, Pengfei Li, Tao Yu
In medical diagnostics, leveraging multiple biomarkers can significantly improve classification accuracy compared to using a single biomarker. While existing methods based on expon…
Receiver operating characteristic curve analysis with non-ignorable missing disease status
Dingding Hu, Tao Yu, Pengfei Li
This article considers the receiver operating characteristic (ROC) curve analysis for medical data with non-ignorable missingness in the disease status. In the framework of the log…
Shape-restricted transfer learning analysis for generalized linear regression model
Pengfei Li, Tao Yu, Chixiang Chen +1
Transfer learning has emerged as a highly sought-after and actively pursued research area within the statistical community. The core concept of transfer learning involves leveragin…
