Nonparametric Bayesian analysis of the accelerated failure time model

Wesley Johnson and Ronald Christensen

Statistics & Probability Letters, 1989, vol. 8, issue 2, 179-184

Abstract: The baseline probability distribution for accelerated failure time is modeled with a Dirichlet process. A fully Bayesian analysis is developed for the estimation of regression coefficients as well as for the estimation of survival curves. The practical difficulties associated with this theoretically desirable analysis are emphasized.
