题 目：Synthesizing secondary data into survival analysis to improve estimation efficiency

报告人：俞童慧（合肥工业大学）

Abstract：In many cases, secondary outcomes are often encountered, which are increasingly available and highly correlated with primary outcomes.  Estimation efficiency from traditional survival models can be further enhanced by incorporating the information from secondary data. We develop an empirical- likelihood-weighted estimation  method to combine a survival model with a secondary model that contains secondary outcomes. Extensive simulation studies and a real data analysis show that the proposed method can gain more efficiency compared to conventional approaches even if the secondary model is misspecified.
