Bayesian reliability analysis of geometric distribution model based on record values |

Abstract: | For the record sample from geometric distribution ,Bayes estimation of reliability was studied under squared error loss and a new weighted square error loss functions .The maximum likelihood estimator and minimum variance unbiased estimator w ere first derived , then Bayes estimators of reliability were obtained when the prior distribution of reliability was conjugate beta prior distribution ,and the loss functions were squared error loss and a new weighted square error loss functions .Finally the effectiveness of the estimators was proposed in this paper by using a Monte Carlo numerical example . |
