Comparing the components of the dominant eigenvalue (slowest eigenvector direction) of the dynamics matrix between patients and healthy controls using a Hotelling T² test.

The eigendirection corresponding to the dominant eigenvalue significantly differed between patients and controls. Single post-hoc test were performed to compare the slowest eigendirection of single mood items. We report mean (M) and standard error of the mean (SEM) ofthe components of the dominant eigenvalue and the results of Mann-Whitney U tests comparing them between patients and healthy controls.
