Bayes estimation of the reliability function and hazard rate of a weibull failure time distribution

SummaryGiven the recorded life times from a Weibull distribution, Bayes estimates of the reliability function and hazard rate are obtained using the posterior distributions and some recent results on Bayesian approximations due to Lindley (1980). Based on a Monte Carlo study, these estimates are compared with their maximum likelihood counterparts.ResumenUtilizando las distribuciones a posteriori y ciertos resultados recientes sobre aproximaciones bayesianas debidas a Lindley, se obtienen estimadores Bayes de la función de fiabilidad, dados los tiempos de vida. Basado en un estudio mediante técnicas de Monte Carlo, estos estimadores se comparan con los máximo verosímiles.
