Survival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in … See more Survival analysis is used in several ways: • To describe the survival times of members of a group • To compare the survival times of two or more groups • To describe the effect of categorical or quantitative … See more The Kaplan–Meier estimator can be used to estimate the survival function. The Nelson–Aalen estimator can be used to provide a non-parametric estimate of the cumulative hazard rate function. See more • Exponential distribution • Weibull distribution • Log-logistic distribution • Gamma distribution See more Survival function The object of primary interest is the survival function, conventionally denoted S, which is defined as Usually one … See more Censoring is a form of missing data problem in which time to event is not observed for reasons such as termination of study before all … See more The textbook by Kleinbaum has examples of survival analyses using SAS, R, and other packages. The textbooks by Brostrom, Dalgaard and Tableman and Kim give examples of survival analyses using R (or using S, and which run in R).

Abstract: This paper characterizes the general behaviors of the MRL (mean residual lives) for both continuous and discrete lifetime distributions, with respect to their failure rates. For the continuous lifetime distribution with failure rates with only one or two change-points, the characteristic ...
