Life Tables and Kaplan-Meier Analysis: Nonparametric Survival

Life Tables and Kaplan-Meier Analysis: Nonparametric Survival Analysis (Statistical Associates Blue Book Series 35)

Life tables refers to a statistical procedure which generates duration (time to event) distributions for an entire dataset or separately for each level of a factor. As such it is a form of nonparametric survival analysis. The primary output is a life table in which the rows are researcher-defined time intervals and the columns have to do with counts, probabilities, and cumulative probabilities of the event of interest occurring during the given time interval.

Kaplan-Meier survival analysis (KMSA) is a method of generating tables and plots of survival or hazard functions for event history data (time to event data). Time to event data might include time to a report of symptomatic relief following a treatment or time to making a contribution following receipt of a fund-raising appeal. KMSA is also a form of nonparametric survival analysis. That is, KMSA is a descriptive procedure for time-to-event variables for use when time is considered the only salient variable.
