关于离散分布无分布检验的注记

Note on distribution free testing for discrete distributions

Estate Khmaladze

摘要:

本文提出了一对一的变换向量的分量$\{Y_{in}\}_{i=1}^m$皮尔逊卡方统计量,\[Y_{in}=\frac{ν_{in}-np_i}{\sqrt{np_i}},\qquad i=1,\ldots,m,\]到另一个向量$\{Z_{in}\}_{i=1}^m$,因此,包含相同的“统计信息”,但渐近分布自由。因此,基于$\{Z_{in}\}_{i=1}^m$的任何函数/检验统计量也是渐近分布自由的。此类检验统计量的自然示例是来自部分和$\sum_{I\leq k}Z_{in}$的传统拟合优度统计量。补充说明了如何在独立利益的问题的方法工程:与齐普夫法和Karlin-Rouault法作为特定的替代品的幂律分布的拟合优度测试。

英文摘要:

The paper proposes one-to-one transformation of the vector of components $\{Y_{in}\}_{i=1}^m$ of Pearson's chi-square statistic, \[Y_{in}=\frac{ν_{in}-np_i}{\sqrt{np_i}},\qquad i=1,\ldots,m,\] into another vector $\{Z_{in}\}_{i=1}^m$, which, therefore, contains the same "statistical information," but is asymptotically distribution free. Hence any functional/test statistic based on $\{Z_{in}\}_{i=1}^m$ is also asymptotically distribution free. Natural examples of such test statistics are traditional goodness-of-fit statistics from partial sums $\sum_{I\leq k}Z_{in}$. The supplement shows how the approach works in the problem of independent interest: the goodness-of-fit testing of power-law distribution with the Zipf law and the Karlin-Rouault law as particular alternatives.
