survival analysis

a family of statistical methods used to model a variety of time-related outcomes. The simplest application of survival analysis involves estimating the amount of time until the occurrence of an event (e.g., death, illness, graduation, marriage) for a group of individuals, but the technique also may be applied to compare durations for two or more groups and to build multivariate models that explain variation in duration. Also called event history analysis.
