WebAbstract. This article describes the combination of multivariate Granger causality analysis, temporal down-sampling of fMRI time series, and graph theoretic … WebMultivariate statistical analysis often begins by identifying a set of features that capture the informa-tive aspects of the data. For example, in fMRI analysis one might select a subset of voxels within an anatomical region of interest (ROI), or select a subset of principal components of the ROI, then use these features for subsequent analysis.
