WebThe predicted canonical correlations range between 0 and 1 where the closer the values to 1, the stronger the correlation between the canonical variates, \(Xa\) and \(Yb\). We can get the variable importance (VIMP) measures for \(Z\). VIMP measures reflect the predictive power of subject-related covariates on the estimated correlations.
