讲座题目: Smoothed jackknife empirical likelihood method for ROC curves with missing data

报告人:    Dr. Yichuan Zhao, Georgia State University

主持人:    郑海涛教授
讲座时间:  2013年6月27日下午4:00

讲座地点:  九里校区电气馆3215

内容概况: In this talk, we apply smoothed jackknife empirical likelihood (JEL) method to construct confidence intervals for the receiver operating characteristic (ROC) curve with missing data. After using hot deck imputation, we generate pseudo-jackknife sample to develop jackknife empirical likelihood. Comparing to traditional empirical likelihood method, the smoothed JEL has a great advantage in saving computational cost. Under mild conditions, the smoothed jackknife empirical likelihood ratio converges to a scaled chi-square distribution. Furthermore, extensive simulation   studies in terms of coverage probability and average length of confidence intervals demonstrate this proposed method has the good performance in small sample sizes. A real data set is used to illustrate our proposed JEL method. This talk is based on joint work with Hanfang Yang.
