R. is the product of the inverse of the correlation matrix of . q’ (Ryy), a correlation matrix between . q’ and . p’ (Ryx), the inverse of correlation matrix of . p’ (Rxx), and the other correlation matrix between . q’ and . p’ (Rxy). Canonical analysis proceeds by solving the above equation for eigenvalues and eigenvectors of the ...

Let R be the correlation matrix of X: R=D-½X’HXD-½/(n-1) where the standard deviation matrix D½=sqrt(diag(X’HX)/(n-1)). Compute R-1. For example, and along the diagonal is 1/(1- 2) which is called the Variance Inflation Factor (VIF). More generally VIFi=(1-Ri2)-1 where Ri2 is the R-square from regressing xi on the k-1 other variables in X.

The Pearson’s correlation matrix should look like the one in Figure 7–4. The cells of the table show the Pearson’s r correlation between each variable and each other variable, the level of statistical significance of the relationship (that is, the likelihood that it could have occurred by chance), and the number of cases on which the ...

Age r = 0.7364 We begin by examining the correlation between age and PCB concentration as well as a scatterplot matrix. The correlation is r = .7364 which is a moderate positive correlation however examination of the scatter plot matrix suggests that the relationship is not linear, thus the correlation really is not an appropriate measure of ...
