多元深度秩和统计量的极限分布及其检验

On the limiting distributions of multivariate depth-based rank sum statistics and related tests

Yijun Zuo, Xuming He

摘要:

基于深度的秩和统计的多变量数据介绍刘和辛格[J. Amer.统计。Assoc.88(1993)252- 260]作为单变量数据Wilcoxon秩和统计量的扩展,已用于质量控制和实验研究中的多变量秩检验。然而,这些应用是基于由Liu和Singh [J. Amer. Statist. Assoc.88(1993)252- 260]。本文在一般正则性条件下证明了该猜想,从而验证了秩和统计量在文献中的各种应用。本文还表明,相应的秩和检验可以更强大的比Hotelling的T^2检验和一些常用的多元秩检验在检测多变量分布的位置尺度的变化。

英文摘要:

A depth-based rank sum statistic for multivariate data introduced by Liu and Singh [J. Amer. Statist. Assoc. 88 (1993) 252--260] as an extension of the Wilcoxon rank sum statistic for univariate data has been used in multivariate rank tests in quality control and in experimental studies. Those applications, however, are based on a conjectured limiting distribution, provided by Liu and Singh [J. Amer. Statist. Assoc. 88 (1993) 252--260]. The present paper proves the conjecture under general regularity conditions and, therefore, validates various applications of the rank sum statistic in the literature. The paper also shows that the corresponding rank sum tests can be more powerful than Hotelling's T^2 test and some commonly used multivariate rank tests in detecting location-scale changes in multivariate distributions.
