报告简介：

Survival analysis provides important approaches for analysing medical data. Particularly, Cox's regression model plays a pivotal rule in survival analysis. In this talk, we will start with a quick introduction to survival analysis and the Cox model, with examples to explain how this model can be used in analysing medical data. Then, after pointing out shortcomings of the partial likelihood method for Cox model fitting, we will proceed to recent developments of likelihood based methods. A simulation study will be included to compare several methods, and finally a real melanoma data example will be explained.
