Interpreting the Correlation Coefficient Study.com

The correlation squared, denoted r2xy , has an interesting interpretation: it is the proportion of the variability in one variable that can be accounted for by a linear function of the other variable.

to conduct what some call a commonality analysis. In such an analysis one can determine how much of the variance in Y is related to the predictors but not included in the p redictors partial or semipartial coefficients. For the Venn diagram above, that is area c. For more details, please see my document Commonality Analysis . A demonstration of the partial nature of multiple correlation and

How to Calculate the Correlation Coefficient ThoughtCo

Pearson's correlation coefficient (r) is a measure of the strength of the association between the two variables. The first step in studying the relationship between two continuous variables is to draw a scatter plot of the variables to check for linearity.

Correlation and Regression Analysis: squared multiple correlation coefficients. One is tolerance, which is simply 1 minus that R2. The second is VIF, the variance inflation factor, which is simply the reciprocal of the tolerance. Very low values of tolerance (.1 or less) indicate a problem. Very high values of VIF (10 or more, although . 8 some would say 5 or even 4) indicate a problem. As
