Title : Laplace Approximation to the Posterior of Bayesian Weibull Model with Time-Varying Effect
Volume, Issue, Year : 7(2)(2019)
Pages : 1−6

Abstract: In this paper, the estimation of the parameter of the Bayesian Weibull model with time-varying effect is considered. The Laplace approximation was developed and compared to the maximum likelihood approach achieved via the Newton-Raphson procedure. The efficiency of the two methods was analyzed using Monte-Carlo samples drawn from the time-varying Weibull model.

Keywords: Bayesian Weibull model, Newton-Raphson procedure, time-varying Weibull model.
