摘要
讨论了在定时截尾情形下,将Weibull分布转化成指数分布数据或均匀分布,利用平均剩余寿命构造样本矩,从而得出参数的矩估计。并通过大量的Monte-Carlo数值模拟试验证实了所给方法的可行性。
When the Weibull distribution is transformed to exponential distribution or uniform distribution under multiply type-I, we can use the mean residual lifetime to construct sample moment. Then the moment estimation of the parameter is obtained. By the Mante-Carlo simulation, we show the feasibility of this method.
