秩检验亦称等级检验。一类非参数检验方法。基于样本观测值的秩的统计检验。秩检验使用的统计量，不是直接由样本观测值计算的，而是由样本观测值的秩计算的。常用秩检验有：秩和检验、克鲁斯卡尔一沃利斯检验，威尔科克逊-曼-惠特尼检验，以及秩方差分析和秩相关分析等。

将秩次转换为正态计分，并以此为基础计算检验统计量。
The ranks were transformed into the normal scores by which the test statistics were calculated.
根据这一情况，本文用半参数方法来校正秩次，使两组秩和检验的统计推断更为合理。
Based on the condition, to adjust rank order with semiparametric method for statistical inference is more reasonable in two sample rank test.
