关于直线相关系数计算方法的一点看法

A View on the Calculation Method of the Linear Correlation Coefficient

本文就直线相关系数在单变量分组条件下的传统计算公式提出一点看法。应根据资料的具体情况进行具体计算,才能得出正确的结论。

The idea of the paper is on the traditional ealculation formula of linear correlation coefficient with single arguments in groups. The traditional calculation method usually results in the inflation of the correlation coefficient. The author thinks that we can only get the accurate calculation when it is based on the specific data.
