Survival Analysis (Chapter 7) • Survival (time-to-event) data • Kaplan-Meier (KM) estimate/curve • Log-rank test • Proportional hazard models (Cox regression) • Parametric regression models Survival analysis deals with the distribution of life times, essentially the times from an initiating event such as birth or the start of a job to some terminal event such as death or pension. (a) generalized (Cox-Snell) (b) Schoenfeld (c) martingale We will rst give the de nition of these residuals, and their direct use in assessing model t.
