Statistics & Probability Letters, 1988, vol. 7, issue 1, 41-46

Abstract: Unbiased estimators for cross-product differences are introduced. Using a representation as U-statistic, its asymptotic normality is derived. Based upon cross-product difference statistics, a test of independence against positive trends of TP2 dependence is proposed and its null distribution is derived.
