Average transfer entropy. (a) Average transfer entropy across values of between energy levels at different frequencies. (b) Tendencies of upward (, blue circle markers) and downward (, red triangular markers) transfer entropy values with respect to the distance between frequencies. Solid lines represent a least squares second-order polynomial fit (higher orders show a similar trend) of the values of (blue solid line) and (red solid line) with respect to . We observe how upward transfer entropy values display an important decrease with distance, whereas downward transfer entropy presents slightly larger values for larger distances.
