True positive = It is actually an anxiety disorder, and the predicted outcome is an anxiety disorder.	(2)
False negative = It is actually an anxiety disorder, but the predicted outcome is normal.
False positive = It is actually normal, and the predicted outcome is an anxiety disorder.
True negative = It is actually normal, and the predicted outcome is normal.
Recall = TP/(TP + FN)
Precision = TP/(TP + FP)
Accuracy = (TP + TN)/(TP + FP + FN + TN)
F1-score = 2 * (Recall * Precision)/(Recall + Precision)
