报告题目：Subgroup Analysis for High Dimensional Heterogeneous Survival Data
主讲人：赵慧教授
报告摘要：Heterogeneity frequently occurs in many disease situations and for the situation, it is essential to classify patients into different subgroups and identify the heterogeneous effects subgroup by subgroup.This talk discusses the subgroup analysis for high-dimensionalsurvival data under heterogeneous proportional hazards model and proposes a statistical procedure with the use of the penalized fusion and model averaging techniques. The proposed method can classify study subjects into different subgroups and determine the number of subgroups, the important predictors and their estimated effects simultaneously. Also the theoretical justification ofthe approach is provided, and an extensive simulation study is conducted to evaluate its performance and indicates that it works well in practical situations. In addition, the proposed methodology is applied to a set of cancer data that motivated this study.
