Applied Survival Analysis. Lecture 1 INTRODUCTION TO SURVIVAL ANALYSIS Survival Analysis typically focuses on time to event (or lifetime, failure time) data. Survival analysis is used to analyze data in which the time until the event is of interest. The response is often referred to as a failure time, survival time, or event time.
