From: Characterising high-order interdependence via entropic conjugation
a Resembling the results presented in Fig. 2, the variability among uk is captured mainly by two principal components: one of skew-symmetric character that accounts for the balance between high- and low-order interdependence (PC1), and one of symmetric character that accounts for the overall strength of the interdependence (PC2). b Relationship between O-information, S-information, and interaction information. Results reveal a substantial correlation (∣ρ∣ > 0.5) between symmetric or skew-symmetric high-order measures, which is consistent with the switching nature of the interaction information.
