Model performance per subject, as measured by AUC and MCC.

AUC performance for each subject for both models (SVM and logistic regression) is shown in top panel; chance is noted by the black horizontal line at 0.5. MCC performance for each subject is shown in bottom panel; chance is noted by the black horizontal line at 0. AUC = area under the curve; MCC = Matthews correlation coefficient; SVM = support vector machine.
