摘要
Frailty models are widely used to model clustered survival data arising in multi-center clinical studies, while most of them are constructed in the context of hazard models for survival outcomes. In this talk, we introduce a frailty model framework based on mean residual life regression with random effects (frailties) to accommodate intracluster correlation and provide easy-to-understand interpretations for the effects of prognostic factors on the expected remaining lifetime of patients. A novel hierarchical quasi-likelihood approach is proposed for parameter estimation. We show favorable performance of the new proposal via simulation studies and further illustrate its application with the data from a multi-institutional study of breast cancer.
