Figure 8. Model order selection based on AIC and BIC, and the effect of using ICA time courses compared to original fMRI time courses on estimated GPDC spectra.

Figure 8

Estimated BIC and AIC criteria functions of model order for bivariate (2 time courses) and multivariate (4 time courses) standard MAR model applied to SM and AOD data (a). Displayed criteria functions represent the median over all subjects and runs, and their minima, which were used as a suggested model order, are marked. The comparison of resulting GPDC spectra, when the ICA time courses and the time courses from original data (the mean and the 1st principle component) were used (b).
