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.
