摘要
为提高PearsonⅦ型分布均值参数估计的精度,构造一个以θ的改进估计δα(X)为中心的置信估计Cδα,通过比较Cδα与通常的置信估计C0X的体积和覆盖率,证明了Cδα与C0X的体积相等但Cδα的覆盖率高于C0X,从而得到Cδα优于C0X的结论.
This paper improves confidence set θ of mean for Pearson Ⅶ distribution. Through the use of improved estimator δ a ( X) of θ , confidence set a Cδ is constructed. The set are show to have uniformly higher coverage probability than the usual confidence set C X0 with no increase in volume, therefore a Cδ dominates C X0.
