WebIn statistics, the Pearson correlation coefficient (PCC, pronounced / ˈ p ɪər s ən /) ― also known as Pearson's r, the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation, or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data. It is the ratio between the covariance of … WebJan 26, 2024 · The explicit form of the density is given in the Wikipedia article on the Pearson correlation coefficient: p ( r) = ( 1 − r 2) ( n − 4) / 2 B ( 1 / 2, ( n − 2) / 2) where r is the random variable (the sample correlation), n is the sample size (number of observation-pairs) and B is the (complete) beta function.
