基于变换样本均值的单参数分布的精确推断

Accurate inference for a one parameter distribution based on the mean of a transformed sample

C. S. Withers, S. Nadarajah

摘要:

统计学中的大量推论都是基于对统计量服从正态分布的近似。这样做的误差通常为$O(n^{-1/2})$,当分布严重偏倚或偏斜时,误差可能非常大。本注释说明如何将此误差减少到$O(n^{-(j+1)/2})$,其中$j$是给定的整数。所考虑的情况是当统计量是连续单参数分布的样本值的平均值时,样本经过初始变换。

英文摘要:

A great deal of inference in statistics is based on making the approximation that a statistic is normally distributed. The error in doing so is generally $O(n^{-1/2})$ and can be very considerable when the distribution is heavily biased or skew. This note shows how one may reduce this error to $O(n^{-(j+1)/2})$, where $j$ is a given integer. The case considered is when the statistic is the mean of the sample values from a continuous one-parameter distribution, after the sample has undergone an initial transformation.
