Kendall rank (Kendel level) correlation coefficient 1. Introduction
In statistics, the Kendel correlation coefficient is named after Maurice Kendall, and is often expressed by the Greek letter Tau (Tau. The kender correlation coefficient is a
Study on the correlation coefficient of Pearson's accumulated momentPearson correlation coefficients (Pearson Correlation coefficient) are often used when doing similarity calculations, so how do you understand the coefficients? What is its
It depends on two aspects: the significant level and the correlation coefficient.
(1) The significant level is the P value, which is the first, because if it is not significant, the correlation coefficient is no longer useful, may only be caused by

Similarity between vectors
There are many ways to measure the similarity between vectors. You can use the reciprocal of distance (various distances), vector angle, Pearson correlation coefficient, and so on.
