In this paper we introduce a partial ordering for positive dependent bivariate distributions. Our main result shows that tests of independence based on rank statistics such as Spearman's rho, Kendall's tau, Fisher-Yates' normal score statistic, van der Waerden's statistic and the quadrant statistic become more powerful under increasing positive dependence. …
