A survey of covariance models for censored life data with an application to recidivism analysis

Abstract

A survey is given of techniques for covariance analysis of censored life data. Both parametric and nonpararnetric approaches are reviewed. An application is given to the evaluation of parolee followup data. We examine the effects of covariates, such as age, income, and drug use, on time to rearrest. One of these covariates varies with time. The records of two correctional institutions are compared after adjusting for non-homogeneity of covariate values.
