| 中文摘要: |
| 本文目的是介绍秩和检验及其SAS实现，具体内容包括以下三个方面：①两样本资料的简单线性秩检验；②多样本资料的单因素ANOVA秩和检验；③前述两种情形下的“评分方法”。在前述提及的第三方面内容中，包含十种具体的评分方法。本文结合一个实例并借助SAS软件实现前述提及的第一类秩和检验，对输出结果做出解释，并给出统计结论和专业结论。 |
| 英文摘要: |
| The purpose of this article was to introduce the rank sum test and its SAS implementation. The concrete contents included the following three aspects： ①the simple linear rank test of two-sample data， ②the one-way ANOVA rank sum test of the multi-sample data， ③the "scoring methods" in the aforementioned two situations. In the third aspect above， there were 10 concrete scoring approaches. Based on an example and with the aid of the SAS software， the paper implemented the first-type rank sum test previously， explained the output results， and made statistical and professional conclusions. |
