Pearson Product-Moment Correlation Coefficient in Statistics
The Pearson Product-Moment Correlation Coefficient (PPMCC) is a parametric statistical measure that quantifies the strength and direction of a linear relationship between two continuous random variables using standardized units, typically denoted as $r$. This metric relies on covariance divided by the product of standard deviations to yield a dimensionless value strictly bounded within the interval [-1, 1]. It operates under assumptions of bivariate normality and linearity, serving as the foundational estimator for linear association in inferential statistics.
