mathcs.clarku.eduCorrelation. The correlation ˆ XY of two joint variables Xand Y is a normalized version of their covariance. It’s de ned by the equation ˆ XY = Cov(X;Y) ˙ X˙ Y: Note that independent variables have 0 correla-tion as well as 0 covariance. By dividing by the product ˙ X˙ Y of the stan-dard deviations, the correlation becomes bounded ...
