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