Interpreting the Correlation Coefficient R. Customarily, the degree to which two or more predictors (independent or X variables) are related to the dependent (Y) variable is expressed in the correlation coefficient R, which is the square root of R-square. In multiple regression, R can assume values between 0 and 1.

Now putting the corrected values of X, Y, X2, Y2 and XY in the following formula we get corrected correlation coefficient . r = = = = = = 0.3 . Therefore, the corrected correlation coefficient is 0.3. Thus in this case, the original value of correlation coefficient is not affected. Example 20

Coefficient of multiple correlation (R) gives strength of correlation between predictors and criterion. Coefficient of determination (r2) is amount x and y vary together. Descriminant function analysis is for non-quantitative criterion (predict which group someone will be in)

Multiple Correlation with Two Predictors. The strength of prediction from a multiple regression equation is nicely measured by the square of the multiple correlation coefficient, R2 . In the case of only two predictors, R2 can be found by using the formula (7) In our example, we find

The multiple correlation coefficient, R, indicates that we have a very high correlation of .957 between our response variable and the two explanatory variables. From the R squared value (coefficient of determination) we can see that the model fits the data reasonably well; 91.5% of the variation in the house values can be explained by the ...
