Abstract In this paper, bayesian statistical inference is researched for parameters of mon sorts of reliability life models-exponentiated-weibull distribution, and exponentiated- pois son distribution,which is based on scale squared loss function?linex loss function and Weighted balance function. Supposed that the parametersαandθare given, random variableXbelongs to exponentiate
