Journal ArticleDOI
Measuring the direction and the strength of coupling in nonlinear Systems-a modeling approach in the State space
Balaji Veeramani,K. Narayanan,Awadhesh Prasad,Leonidas D. Iasemidis,Andreas Spanias,K. Tsakalis +5 more
TL;DR: Through a surrogate analysis, it is shown that the proposed method is more reliable than the directed transfer function in identifying the direction and strength of the involved interactions.
Journal ArticleDOI
Block time and frequency domain modified covariance algorithms for spectral analysis
TL;DR: The authors develop the block modified covariance algorithm (BMCA) which can be implemented either in the time or in the frequency domain-with the latter being more efficient in high-order cases.
