截尾数据下威布尔分布的参数估计问题

Parameter Estimation of Weibull Distribution with Censored Data

针对截尾寿命试验数据对相关寿命分布及其参数进行统计推断问题,根据可靠性统计理论,研究了在截尾数据条件下,威布尔分布中的形状参数β及特征寿命参数η的点估计和区间估计.结合实例,验证了估计方法的可行性,可供可靠性工程界作为参考.

For estimating the parameters of the various life distribution by censored test data in the reliability engineering, on the basis of the life testing data of censored test,the paper gives the parameter estimation methods of the characteristics shape parameter β and life parameterη in Weibull distribution,which is based on the reliability statistics theorietics. By means of the example, the estimation methods are proved to be feasible. The methods also can be applied in reiliability engineering.
