... – randomly "sample" all the m+n observations so there are m in group1 and n in group2. – compute the difference between the means of the two groups of the "sampled" vector, D. – repeat this procedure a large number of times (1000 or larger). For an upper-tailed test, calculate the empirical p-value: ...
