相关系数信息在实证研究中的综合利用

The Comprehensive Utilization of Correlation Coefficient Information in the Empirical Study

相关系数是统计学中非常重要的概念,统计学经常是要研究相关,寻找相关,相关系数不仅提供了相关程度与方向,更重要是利用相关关系得到辅助信息。本文阐述如何在实证研究中综合利用相关系数信息,多角度分析了利用相关系数所提供的辅助信息的场合与方法,对全面认识相关系数,如何避免伪相关具有重要意义。

Correlation coefficient is a very important concept in statistics. Most purposes of statistics are to research and find relevant information between variables. Correlation coefficient not only provides the related degree and direction. More importantly, it can get useful auxiliary information by correlation. This paper describes how to make use of correlation coefficient information in empirical research. It analyzes occasion and method which use auxiliary information provided by correlation coefficient from multiple perspectives. For an overview of the role of correlation coefficient, how to avoid spurious correlation is of great significance.
