Fig. 2

Eigen-decomposition analysis of PPP phenomenon for a linear model. The left figure shows the eigenvalues of the true and estimated DCM with one separated from the bulk. The right figure shows the eigenvector corresponding to the separated/dominating eigenvalue for both the true and estimated DCM, the latter of which is shown to align closely with the normalized data vector.
