| Abstract: | For threefold piecewise Weibull distribution model, an optimal selection principle is proposed under type-II censored sample, and then the inverse moment estimates and interval estimates of parameters are obtained. In addition, some examples are illustrated to show the convenience and feasibility of the method. |

| Keywords: | Weibull distribution threefold piecewise model maximum likelihood principle inverse moment estimate interval estimate |
