Abstract:Frailty model is a survival model designed to account for unobserved heterogeneity in the population. In this paper, we propose a new shared frailty model based on log-logistic as baseline distribution. The Bayesian approach of Markov Chain Monte Carlo (MCMC) technique was employed to estimate the parameters involved in the models. A simulation study was performed to compare the true values and the estimated values of the parameters. Comparison of different proposed models was done by using Bayesian comparison… Show more
