Direct directed transfer function
WebDirected Transfer Function (DTF) [10] and direct Directed Transfer Function (dDTF) [11] are MVAR-based measures that have been introduced to determine directional influence in multivariate systems. They have also been validated using simulated models [7, 9, 12]. The original versions of these measures assume that the underlying WebAbstract: In this article we briefly investigate the Directed Transfer Function, the DTF, a causality measure used in determination of brain connectivity patterns, …
