摘要
The Weibull failure model is considered in this paper. Some testimators are proposed of the scale parameter (beta) and of the reliability function (R(t)) using life-testing data when a prior value about the unknown parameter (beta) is available. The expressions for the bias, mean squared error and relative efficiency are obtained and compared with existing estimators.
