## jaccard相似系数（Jaccard similarity coefficient）

jaccard相似系数 jaccard相似系数（Jaccard similarity coefficient）主要应用场景为数据聚类、比较文本的相似度，用于文本的查重与去重，计算对象间的距离。 jaccard相似系数用于比较有限样本集之间的相似性和差异性J(A,B)为A与B交集的大小与A与B并集的大小的比值。 实例 s1={1，3，4，5，7，8，9}，s2={1，2，3，5，6...

## linear correlation coefficient|Correlation and Causation|lurking variables

4.4 Linear Correlation 若由SxxSyySxy定义则为： 所以为了计算方便： 所以，可以明白的是，Sxx和Sx是不一样的！ 所以，t r is independent of the choice of units and always lies between −1 and 1 Understanding the Linear Correlation Coefficient measures the strength of the linear relationship between two...
