由公式可知,Pearson相关系数是用协方差除以两个变量的标准差得到的,虽然协方差能反映两个随机变量的相关程度(协方差大于0的时候表示两者正相关,小于0的时候表示两者负相关),但是协方差值的大小并不能很好地度量两个随机变量的关联程度,例如,现在二维空间中分布着一些数据,我们想知道数据点坐标X轴和Y轴的相关程度,如...
>>> python3 setup.py install This will install the module to the appropriate directory for third-party modules. DESCRIPTION WPCC contains a single function (wpearson), that allows users to calculate a weighted Pearson Correlation Coefficient for two vectors. This was primarily written to find gen...
Pearson correlationis the most used one. correlation formulais describedhere. Negative and positive correlation The value ofcorrelation coefficientcan benegativeorpositiveand it is comprised between-1and1(see the plots below). -1means strongnegative correlation: In this case y decreases when x increas...

(Additional file 1: Figure S2), we find that this assumption is confirmed, but only partially: similarity measures, where we can observe major differences are Mic (Michael), HD (Hawkins–Dotson), Den (Dennis), dis (dispersion), SS4 (Sokal–Sneath 4), Phi (Pearson–Heron), Coh (Cohen)...
