Abstract: Maximum likelihood estimation of the parameter is given under type-II censoring samples on Эрланга distribution; Then we discuss the Bayesian estimation of the parameter under Linex、quadratic、square and balanced loss functions, and prove that the estimates we have derived are admissible; At last, we analysis the accuracy of estimators by means of specific examples.
Key words:Эрланга distribution; loss function; Bayesian estimate
