The prototypical suchevent is death, from which the name Survival analysis and much of its terminology derives, but theambit of application of Survival analysis is much broader. Essentially the same methods are employedin a variety of disciplines under various rubrics for example, event-history analysis in sociologyand failure-time analysis in engineering.
The Cox proportional-hazards regression model is the most common tool for studying the dependency of survival time on predictor variables. This appendix to Fox and Weisberg (2019) brie y describes the basis for the Cox regression model, and explains how to use the survival
