WebThe effect size r is calculated as Z statistic divided by square root of the sample size (N) ( Z / N ). The Z value is extracted from either coin::wilcoxsign_test () (case of one- or paired-samples test) or coin::wilcox_test () (case of independent two-samples test). Note that N corresponds to total sample size for independent samples test and ...
