As seen in Fig. 5, the heatmap displays the correlation coefficients between entropy and indices, indicating either positive or negative correlations between them. Figure 6a depicts an intriguing situation in which the Pearson correlation coefficient between all indices is precisely 1. A heat map...

在统计学中,皮尔逊相关系数相关系数(英语:Pearson product-moment correlation coefficient,又称作 PPMCC 或 PCCs, 用 r 表示)用于度量两个变量 X 和 Y 之间的相关(线性相关),其值介于 -1 与 1 之间。-1 表示完全的负相关(这个变量下降,那个就会上升),+1 表示完全的正相关,0 表示没有线性相关。通常情况下...
