aThree nonparametric methods are Spearman’s nonparametric correlation coefficient, Kendall tau rank correlation coefficient and Hoeffding’s inequality
-
bcorrelation coefficients marked with “++” are statistically significant by all three methods; those marked with “+” are statistically significant by two of three methods
-
cindicates no significant difference
