Generalized Topp-Leone-Weibull AFT Modelling: A Bayesian Analysis with MCMC Tools using R and Stan

The generalized Topp-Leone-Weibull (GTL-W) distribution is a generalization of Weibull which obtained by using Topp-Leone (GTL) as generator and considering baseline distribution. widely used survival model that has monotone- increasing or decreasing hazard. But it cannot accommodate bathtub shaped unimodal hazards. As model, GTL-W more flexible than the to different types present study aims at fitting an accelerated failure time (AFT) censored data under Bayesian setting R Stan languages.
