Evaluating how well Hallmark genes are linked to GWAS-identified 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)
Hallmark	GWAS-identified	0.99	13.65	8.35	3.57	7.83
GWAS-identified	Hallmark	1.00	2.71	6.51	2.70	4.03

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)
Hallmark	GWAS-identified	0.12	597.09	175.16	180.85	194.45
GWAS-identified	Hallmark	0.07	88.38	273.70	113.86	186.15

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
