Abstract

Este trabalho apresenta uma inferência bayesiana da distribuição Weibull discreta em dados com presença de censuras.  Foi proposto também um teste de significância genuinamente bayesiano (FBST – Full Bayesian Significance Test) para testar o seu parâmetro de forma. As distribuições a posteriori dos parâmetros foram obtidas por meio de simulações via Markov Chain Monte Carlo (MCMC) e a metodologia desenvolvida foi ilustrada em simulações e aplicada em um conjunto de dados sobre o tempo de sobrevivência de homens diagnosticados com AIDS. Todas as simulações e obtenções das estimativas foram realizadas através do software free R.
