本文讨论了观测向量元素完全独立性的检验问题。Schott提出了检验算子T,并在样本大小和维数p趋于无穷大且p/n收敛于一个正常数的高维渐近框架下,给出了极限零分布.在这篇文章中,我们给出了一个一项渐近展开的零分布tastends向无穷大。我们推导出一个修正的临界点的Schott的测试的基础上,这种扩展。有限的样本容量和维数性能达到的显着性水平进行了评估,在模拟研究和结果进行了比较,肖特的检验。
This article is concerned with the testing complete independence for the elements of observed vector. Schott proposed the testing statisticTand gave limiting null distribution under the high-dimensional asymptotic framework that the sample sizenand the dimensionalitypgo to infinity together whilep/nconverges to a positive constant. In this article we give a one-term asymptotic expansion of the null distribution forTastends toward infinity. We derive a correction of the critical point for Schott’s test based on this expansion. The finite sample size and dimensionality performance for attained significance level is evaluated in a simulation study and the results are compared to those of Schott’s test.
