“…Here, differences greater than two standard errors are deemed significant corresponding to an asymptotic significance level of approximately 0.05. For our second comparison, we let y be the correlation coefficient of a bivariate normal distribution and we consider tests of significance based on the Kendall rank correlation coefficient, K, and the Spearman rank correlation coefficient, S. Chow, Miller and Dickinson (1974) compared these power functions but were unable to determine which procedure is preferable. To facilitate such comparisons, we performed randomized tests (cr=0.05) and use the more accurate estimate of standard error, SE(C).…”
