The Wilcoxon Rank Sumtest, also called the Mann Whitney U Test, is a non-parametric test that is used to compare themediansbetween two populations. In other words, it tests if two samples are likely to be from the same population. It performs a similar function as the two-sample independ...
WCRIT(n1,n2,α,tails, interp) = critical value of the Wilcoxon Rank-Sum test for samples of sizen1andn2for the given value of alpha (defaultα= .05) andtails= 1 (one tail) or 2 (two tails, default) based on theWilcoxon Rank-Sum Table. WPROB(x, n1, n2, tails, iter, interp)...
The p-value of Wilcoxon’s Rank-Sum one-tail test for test statisticWand sample sizesn1 andn2 is given by the formula PERM2DIST(MIN(W, W’),n1,n2, TRUE, FALSE). The critical value for any value of alpha is PERM2INV(α,n1,n2, FALSE). The two-tail test is given by 2*PERM2D...
The rule is quite simple if k is the value on the Mann-Whitney Table, then the critical value for the Wilcoxon Rank-Sum test is k+m(m+1)=2 where m is the smaller of the two samples sizes. E.g. for alpha = .05 and n1 = 10 and n2 = 12, the critical value on the Mann-Wh...

Wilcoxon 检验之 rank-sum 与 signed-rank ” 当然就是指 “将排名进行求和”的操作。在秩和检验中,我们不要求被检验的2组数据包含相同个数的元素,换句话说,秩和检验更适用于非成对数据之间的差异性检测。数据...Wilcoxonrank-sum test(我翻译为秩和检验)和Wilcoxonsigned-rank test(我翻译为符号秩检验)。今天...
