Briefly discuss how the magnitudes of the elements in the shrinkage variance$-$covariance matrix compare with those in sample variance$-$covariance matrix. $($Examine the diagonal elements and the off$-$diagonal elements.$)$

Briefly comment on a comparison of the weights of the GMVP estimated using the shrinkage variance$-$covariance matrix versus those estimated using the sample variance$-$covariance matrix.
