WebJun 3, 2013 · Thanks again If this was true, the 'wilcox.exact' function would be completely pointless since 'wilcox.test' just falls back on the asymptotic approximation when ties are present. Software like 'StatXact', 'exactRankTests', and 'coin' use algorithms that compute the exact p-value for any ties configuration. Webwilcox_test() returns a Z transformation of the statistic returned by wilcox.test(), which is why they have different values of the test statistic. Is there a correct p-value? Yes, but … multiverse arrowverse wiki
