  1. The EMA used all features and applied to recordings that passed strict artefact detection. MSE is the means square error, r is the adjusted correlation coefficient (linear mixed model), electrode locations are Fp – frontal polar, C – central, T – temporal, O – occipital, and montages are symmetric across hemispheres. The p-value is estimated using a Wilcoxon signed rank test for paired data, n = 101; the null hypothesis tested is that the MSE was not different from that estimated using an 8-channel EEG montage.
