基于逐步增加的Ⅱ型截尾,讨论了Pareto分布形状参数和尺度参数的区间估计.得到了两参数的区间估计和联合区间估计.最后以估计区间的最短长度为标准,通过数值模拟得到参数的最优区间估计方法.%The interval estimation of the parameter θ and the joint confidence region of the two parameters of Pareto distribution based on the progressive type Ⅱ censored are proposed. Finally, the statistical performances of the three methods are compared to by obtaining a smaller confidence area based on Monte-Carlo simulation study.
