Table 1.

Performance of PennCNV-Seq regarding different number of copies for CNVs: deletions with 0 or 1 copy, and duplication with 3 or 4 copies, and loss-of-heterozygosity (LOH)

No. of copies	Precision	Recall
0 copy (hom. deletion)	0.814	0.399
1 copy (het. deletion)	0.711	0.665
3 copy (het. duplication)	0.962	0.528
4 copy (hom. duplication)	0.732	0.416
Loss-of-heterozygosity (LOH)	1.000	0.650

Precision is TP/(TP+FP) and Recall is TP/(TP+FN), where TP=True Positive, FP=False Positive and FN=False Negative
