逐步增加的Ⅱ型删失下Lomax分布的参数估计

Estimation of the Parameters for Lomax Distribution based on Progressively Type-Ⅱ Censored Data

在逐步增加的Ⅱ型截删失样本下,通过构建统计量得到了Lomax分布中两参数的逆矩估计和区间估计,并利用随机模拟的方法说明了所给估计的精度.

In this paper,we obtain the inverse moment estimation and interval estimation of the two parameters in the Lomax distribution by constructing the statistics Based on the progressively type-Ⅱ censored samples,the accuracy of the estimation is illustrated by the method of stochastic simulation.
