Pearson correlation coefficient 中文
WebThe Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable. A value less than 0 indicates a ... http://www.cjig.cn/html/jig/2024/3/20240305.htm
