Abstract In this chapter, we discussed the estimation of the unknown parameters (, , p) of the Weibull-Geometric distribution and the acceleration parameter , based on constant partially accelerated life tests. Based on a progressive first-failure censored sample the maximum likelihood and the Bayes estimates are obtained. It is observed that the Bayes estimators cannot be obtained in explicit forms and they need complicated integrals to be performed numerically. Because of that, the MCMC method, namely the Metropolis-Hastings sampling technique, is applied to obtain the Bayes estimates under squared error and Linex loss functions. from the results, in Tables (5.1) - (5.4), it can be observed that the Bayes estimates under the symmetric (SEL) and the asymmetric (Linex) loss functions are better than their corresponding MLEs. It can also be seen that the mean squared errors decrease as the sample sizes increase. Also there is no large effect of exchanging the censoring scheme on results. Note: Some results of this chapter have been submitted for publications in Assiut University Journal of Mathematics and Computer Science under the title ”Estimation for the Weibull-Geometric Distribution based on constant partially accelerated life tests via MCMC technique”. |
