Statistical Analysis of Single-Trial Granger Causality Spectra
Figure 6
Simulation 3. (a) Granger causality p-spectra. Boxplot of the -values associated with the linear regressions performed at each frequency between the log-transformed Granger causality spectra and the coupling strengths varying across trials. (b) Boxplot of the -values plotted over the number of trials simulated in each dataset. (c) Statistical power curves at three levels of significance α = 0.01, 0.001, and 0.0001 as a function of the number of trials used in each session.
