This paper presents estimates for the parameters included in the Block and Basu bivariate lifetime distributions in the presence of covariates and cure fraction, applied to analyze survival data when some individuals may never experience the event of interest and two lifetimes are associated with each unit. A Bayesian procedure is used to get point and confidence intervals for the unknown parameters. Posterior summaries of interest are obtained using standard Markov Chain Monte Carlo methods inrjagspackage forRsoftware. An illustration of the proposed methodology is given for a Diabetic Retinopathy Study data set. [ABSTRACT FROM PUBLISHER]
