Abstract |
|
|
| This paper describes the Bayesian inference and prediction of the generalized Pareto (GP) distribution for progressive firstfailure
censored data. We consider the Bayesian inference under a squared error loss function. We propose to apply Gibbs sampling
procedure to drawMarkov ChianMonte Carlo (MCMC) samples, and they have in turn, been used to compute the Bayes estimates with
the help of importance sampling technique. We have performed a simulation study in order to compare the proposed Bayes estimators
with the maximum likelihood estimators. We further consider two sample Bayes prediction to predicting future order statistics and
upper record values from generalized Pareto (GP) distribution based on progressive first-failure censored data. The predictive densities
are obtained and used to determine prediction intervals for unobserved order statistics and upper record values. A simulated data set is
used to illustrate the results derived. |
