【摘要】 作者对Wilcoxon符号秩和检验法和Wilcoxon两样本秩和检验法作了一些改进,给出了相应的两个临界值表,作为在小样本的情况下进行显著性检验时确定P值的依据。本文用两个实际例子说明改进后的Wilcoxon秩和检验法的具体步骤。更多还原

【Abstract】 We have made a number of impr-ovements in Wilcoxon signed rank sum test for two samples. Two tables of critical values are given for determination of P values when the sample size is small. The method is illustrated with two practical examples.更多还原
