Explore Stata's survival analysis features, including Cox proportional hazards, competing-risks regression, parametric survival models, features of survival models, and much more.
Survival analysis models factors that influence the time to an event. Ordinary least squares regression methods fall short because the time to event is typically not normally distributed, and the model cannot handle censoring, very common in survival data, without modification. Nonparametric methods ...

SAS/STAT Software Survival Analysis. Data that measure lifetime or the length of time until the occurrence of an event are called lifetime, failure time, or survival data. For example, variables of interest might be the lifetime of diesel engines, the length of time a person stayed on a job, or the survival time for heart transplant patients.
