逐次定数截尾下Weibull分布参数的逆矩估计

摘要

基于逐次定数截尾样本下,讨论了两参数Weibull分布的参数估计,得到了两参数的逆矩估计.并利用模拟方法与极大似然估计作比较,模拟结果表明逆矩估计优于极大似然估计.%In this article, obtains the inverse moment estimate of the two parameters of Weibull distribution based on the progressive Type II censored. Finally, using Monte -Carlo method, compare the proposed estimators with the maximum likelihood estimators. The results show that the proposed estimators outperform the maximum likelihood estimation.
