Pearson's product moment correlation defined

WebThe Pearson correlation is defined only if both standard deviations are finite and positive. An alternative formula purely in terms of moments is: Correlation and independence [ edit] It is a corollary of the Cauchy–Schwarz inequality that the absolute value of the Pearson correlation coefficient is not bigger than 1.
