Figure 6

The causality analysis of the preictal period. The causality 𝑐(𝑖→𝑗) corresponds to the row 𝑖 and the column 𝑗. The order is chosen as 𝑚=6 according to the AIC criterion. (a) Bivariate analysis. (b) Our approach with 𝑛_𝑑=5 conditioning variables. (c) Our approach with 𝑛_𝑑=20 conditioning variables. (d) The multivariate analysis.
