Introduction: survival and hazard Survival analysis is the branch of applied statistics dealing with the analysis of data on times of events in individual life-histories (human or otherwise).

I Instead of looking at the cdf, which gives the probability of surviving at most t time units, one prefers to look at survival beyond a given point in time. Week 2: Non-Parametric Estimation in Survival Models. The second distinguishing feature of the eld of survival analysis is censoring: the fact that for some units the event of interest has occurred and therefore we know the exact waiting time, whereas for others it has not occurred, and all we know is that the waiting time exceeds the observation time. Fraser Blackstock. In survival analysis the outcome istime-to-eventand large values are not observed when the patient was lost-to-follow-up before the event occurred.
