| Abstract: | Based on censored samples, the problem of moment estimation of the three-parameter Weibull distribution is discussed. Mean residual lifetime is used to constructed sample moment. With the method of transformation, the modified moment equation is derived. Especially, together with geometric mean, we set up the first equation, which makes the outcome more precise. |
