Bayesian and non-bayesian estimation for weibull parameters based on generalized type-ii progressive hybrid censoring scheme

Bayesian and non-bayesian estimators are obtained for the unknown parameters of weibull distribution based on the generalized type-ii progressive hybrid censoring scheme and different special cases are obtained. the asymptotic variance covariance matrix and approximate confidence intervals based on the asymptotic normality of the maximum likelihood estimators are obtained. bayes estimates and bayes risks have been developed under a squared error loss function using informative and non-informative priors for the unknown weibull parameters. it is observed that the estimators obtained are not available in closed forms,although they can be easily evaluated for a given sample by using suitable numerical methods. therefore,a numerical example is considered to illustrate the proposed estimators.
