Abstract

Time-to-event data are abundant in many fields: time to death or relapse in a medical setting, time to graduation or recidivism in social sciences or time to breakdown of machine parts in an industrial setting. Clearly, the time to an event can only be observed for those who already experienced the event of interest: your refrigerator broke down after 5.2 years, while your oven is still operational after 8 years. For the latter, we only know the time to breakdown is more than 8 years. Where standard regression techniques mishandle the information from these censored observations, Survival analysis efficiently uses all available information in a correct way. Day 1 introduces the basic concepts of Survival analysis, illustrated with hands on computer labs in R. Day 2 discusses the specificities of sample size calculations for time-to-event data, with standard approaches in R and SAS, more flexible approaches in STATA and an introduction to building simulations to test the impact of various deviations from the basic assumptions. Computer labs will be in R only.
