Detailed Description

Partial Directed Coherence estimator (Baccala & Sameshima 2001); directional, direct paths only.

Partial Directed Coherence estimator of Baccala & Sameshima (2001).

Computes PDC_{ij}(f) = |A_{ij}(f)| / sqrt( sum_k |A_{kj}(f)|^2 ) from the MVAR coefficients delivered by MvarModel, where A(f) is the frequency-domain inverse of the transfer matrix. Unlike DirectedTransferFunction this estimator counts only direct causal paths - relayed interactions j -> k -> i contribute 0 - so PDC and DTF together separate direct from indirect flow.
