      The correlation between Y( and the actual Y value is also called the multiple correlation coefficient, Ry.12...k, or simply R. Thus, R provides a measure of how well Y can be predicted from the set of X scores. The following formula can be used to test the null hypothesis that in the population there is no linear relationship between Y and ...
