在統計學中，皮爾森積動差相關係數（英語：Pearson product-moment correlation coefficient，縮寫：PPMCC，或PCCs ，有時簡稱相關係數）用於度量兩組數據的變數X和Y之間的線性相關的程度。它是兩個變數的共變異數與其標準差的乘積之比； 因此，它本質上是共變異數的歸一化度量，因此結果始終具有介於-1和1之間的值。與共變異數本身一樣，該度量只能反映變數的線性相依 … chart for cuts of beefWeb2 两个重要的相关系数——Pearson & Spearman 2.1 Pearson Correlation Coefficient(皮尔逊相关系数) Wikipedia Definition: In statistics, the Pearson correlation coefficient also referred to as Pearson’s r or the bivariate correlation is a statistic that measures the linear correlation between two variables X and Y.It has a value between +1 and −1. currys pc world food processorsWeb基本概念.
