Table 1

Cross table of true against predicted classification (1 = observation belongs to the subgroup according to the corresponding classification; 0 = otherwise).

		Classification of the algorithm
		1	0
True	1	True positives (TP)	False negatives (FN)
Classification	0	False positives (FP)	True negatives (TN)
