Wilcoxon W是Wilcoxon rank sum test 检验中的秩和值。Wilcoxon秩和检验在Matlab中，秩和检验由函数ranksum实现。命令为： [p,h]=ranksum(x,y,alpha) 其中x，y可为不等长向量，alpha为给定的显著水平，它必须为0和1之间的数量。p返回产生两独立样本的总体是否相同的显著性概率，h返回假设 正文 1 Z是标准化...

The p-value is derived from comparing a test-statistic (in this case a z-value obtained by summing ranks) to a theoretical distribution. The p-value is an estimation of the chance of observing the data given the null-hypothesis being true. If this value is below a certain criterion (...

I would like to evaluate the null-hypothesis for two matrices, specifically to make a Mann-Whitney test with them. I found the Ranksum (Wilcoxon test) function, but it only works with vectors. Is there any function that could allow me to do the test for the matrices? Thanks1...
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*PERM2...
