In a multipleregression model R-squared is determined by pairwise correlations among allthe variables, including correlations of the independent variables with each other as well as with the dependent variable. In the latter setting, the square root of R-squared is known as “multiple R”, and it is equal to the WebCaution # 1. The coefficient of determination r2 and the correlation coefficient r quantify the strength of a linear relationship. It is possible that r2 = 0% and r = 0, suggesting there is no linear relation between x and y, and yet a perfect curved (or "curvilinear" relationship) exists.
