Table 1. Results from fourfold cross-validation in single-subject recordings (intrasubject CV) and from leave-one-subject-out cross-validation with multiple-subject recordings (intersubject CV).

MLR with four band area features and PLS regression with full-range spectra were used. CEG, consensus error grid.
