定数截尾缺失数据下Weibull分布的形状参数近似估计

Approximate Estimation for the Shape Parameter of Weibull Distribution under Multiply Type-Ⅱ Censoring

研究定数截尾寿命试验数据缺失场合下,Weibull分布中形状参数的点估计问题.利用次序统计量的方法给出形状参数的近似估计,并通过大量的Monte-Carlo数值模拟试验,验证方法的可行性.

In this paper,we study the point estimation for the shape parameter of Weibull distribution under multiply type-Ⅱ censoring.The approximate point estimation of unknown parameter is obtained by using the method of order statistics.By the Monte-Carlo simulation,the precision for the parameter estimation under a large amount of samples is satisfied.
