Abstract: 
Survival analysis is a branch of statistics that studies time-to-event data or survival data. The main feature of survival data is that the response variable is only partially observed and subject to censoring and/or truncation caused by the nature of study design. In this talk, I will briefly discuss different types of survival data and existing popular semiparametric survival models in the literature. Then I will discuss my recent work in detail on regression analysis of arbitrarily censored data and left truncated data. The proposed estimation approaches are developed based on EM algorithms and enjoy several nice properties such as being easy to implement, robust to initial values, fast to converge, and providing variance estimates in closed form.
