ROC curves for different connectivity metrics. (a) ROC curve of Granger’s causality. (95% CI 0.004-0.996 ). (b) ROC curve of the Pearson . Delta (95% CI 0.540-0.573 ), theta (95% CI 0.611-0.643 ), alpha (95% CI 0.726-0.754 ), and beta (95% CI 0.480-0.513 ). (c) ROC curve of PTE. Delta (95% CI 0.746-0.766 ), theta (95% CI 0.833-0.849 ), alpha (95% CI 0.700-0.721 ), and beta (95% CI 0.876-0.890 ). (ROC: receiver operating characteristic curve; AUC: area under curve; PTE: phase transfer entropy).
