| 中文摘要: |
| 本文目的是介绍Pearson相关系数、Spearman秩相关系数和Kendall’s tau-b秩相关系数的概念及应用场合。首先介绍三种相关系数的计算及其假设检验的基本原理，然后使用SAS程序对实例进行分析，最后对分析结果进行解释和讨论。 |
| 英文摘要: |
| The purpose of this article was to introduce the concepts and application situation of Pearson’s correlation coefficient, Spearman’s rank correlation coefficient and Kendall’s tau-b rank correlation coefficient. Firstly, this article introduced the basic statistical principles of the three kinds of correlation coefficients, then SAS software was used to perform the correlation analysis of the example, and finally the analyzed results were explained and discussed. |
