Addressing Indirect Functional Connectivity in Neuroscience via Graphical Information Theory: Causality and Coherence
… (1) causality in the time domain and (2) coherence in the frequency domain that scale markedly better and thereby enable minimization of indirect functional connectivity. Our first model-free framework, graphical directed information (GDI), enables pairwise directed functional connections …

Detection of multiple correlated time series and its application in synthetic aperture sonar imagery
… The solution is attained by considering a Generalized Likelihood Ratio Test (GLRT) that tests the null hypothesis that the composite covariance matrix of the channels, a matrix containing all inter and intra-channel second-order information, is block-diagonal. The test statistic becomes a …
