Extended tables of critical values for Wilcoxon's test statistic
Wilcoxon 检验统计量临界值表的扩展
New tables of exact critical values of Wilcoxon's rank sum test statistic W for the two-sample problem are presented for lower significance levels 0.001, 0.005, 0.01, 0.025, 0.05, 0.10 and sample sizes m≤ n = 1(1) 25. Two approximations for calculating Pr(W ≤W) are discussed. When ties are present in the samples, one can use an approximation. In the Appendix the errata are given for errors found in earlier published tables.
