Pearson similarity index

13 Nov 2019 The Pearson's correlation coefficient \rho_{U,V} aims to measure the strength of a linear relationship between two random variables U and V The Karl Pearson's product-moment correlation coefficient (or simply, the Pearson's correlation coefficient) is a measure of the strength of a linear association Linear correlation between variables. The Pearson correlation coefficient is computed as: As we can see, the correlation coefficient is just the covariance (cov ) Items 1 - 40 of 43 Pearson's correlation coefficient does not suggest a cause-and-effect relationship between two variables. It cannot be interpreted as a proportion, The Pearson product-moment correlation coefficient is measured on a standard scale -- it can only range between -1.0 and +1.0. As such, we can interpret the pearson : standard correlation coefficient. kendall : Kendall Tau correlation coefficient. spearman : Spearman rank correlation. callable: callable with input two 1d

The Pearson and Spearman correlation coefficients can range in value from −1 to +1. For the Pearson correlation coefficient to be +1, when one variable increases

If you are looking for trend or shape similarity, then go with correlation. Also note, that if you perform z-score normalization in each object, Euclidean Distance behaves similarly to Pearson correlation coefficient. Pearson is not sensitive to linear transformations of the data.
