Directed Q-Analysis and Directed Higher-Order Connectivity on Digraphs: A Quantitative Approach
Heitor Baldo, Luiz A. Baccalá, André Fujita +1
Traditional graph analysis focuses on nodes and edges, that is, pairwise relationships. Yet many real-world networks, including biological, social, and communication networks, invo…
Partial Directed Coherence and the Vector Autoregressive Modelling Myth and a Caveat
Luiz Antonio Baccalá, Koichi Sameshima
Here we dispel the lingering myth that Partial Directed Coherence is a Vector Autoregressive (VAR) Modelling dependent concept. In fact, our examples show that it is spectral facto…
Consolidating a Link Centered Neural Connectivity Framework with Directed Transfer Function Asymptotics
Luiz A. Baccalá, Daniel Y. Takahashi, Koichi Sameshima
We present a unified mathematical derivation of the asymptotic behaviour of three of the main forms of \textit{directed transfer function} (DTF) complementing recent partial direct…
Information theoretic interpretation of frequency domain connectivity measures
Daniel Yasumasa Takahashi, Luiz Antonio Baccalá, Koichi Sameshima
To provide adequate multivariate measures of information flow between neural structures, modified expressions of Partial Directed Coherence (PDC) and Directed Transfer Function (DT…
