Fig. 1: High-order interdependencies in the W-distribution.
From: Characterising high-order interdependence via entropic conjugation

Description of the interdependencies within n = 7 binary variables considering a mixture of n identical bits (COPY) and an n-th order exclusive-or (XOR) given by the uk quantities. As expected, the effects of the mixture are tracked by the terms corresponding to the lowest- and highest-order interactions. In the figure, continuous and dotted lines are used for enhancing visual clarity.
