Evaluating how well GroupA genes are linked to GroupB genes, comparing against random

ROC results
Seeds	Recipients	AUROC	Z-score for Random Seeds (degree-matched)	Z-score for Random Recipients (degree-matched)	Z-score for Random Seeds (uniform)	Z-score for Random Recipients (uniform)

PRC results
Seeds	Recipients	AUPRC	Z-score for Random Seeds (degree-matched)	Z-score for Random Recipients (degree-matched)	Z-score for Random Seeds (uniform)	Z-score for Random Recipients (uniform)
GroupA	GroupB	0.00	0.08	0.85	0.23	0.86
GroupB	GroupA	0.00	0.00	-0.37	-0.28	-0.17

Z-scores are computed for the experimental area under ROC or PRC based on distributions of the random areas under these curves
Seeds: Genes where diffusion signal starts FROM)
Recipients: Genes that receive the diffusion signal and that are in the other validated group
Random genes are selected either uniformly or degree matched
