Evaluation of the reference index.

	Training sample	Test sample	Output sample	Correct sample	Precision (%)	Recall (%)	Gm (%)
D
Positive	553	138	128	124	96.0	90.0	93.43
Negative	1150	287	296	282	95.38	98.19
E
Positive	552	138	136	128	94.10	92.82	93.98
Negative	552	138	140	130	92.87	94.12

Note: D: sample set has different numbers of positive and negative samples; E: the sample set has equal numbers of positive and negative samples; correct sample: the number of correct predictions.
