  1. The table provides the average AUROC scores across 25 data sets for a network of p = 100 nodes with 3% of true positives edges and varying sample size n
  2. *Two-sides t-test between the ‘un-shrunk’ and ‘shrunk’ methods statistically significant at 0.05
  3. **STAR model selection is used from the R package ‘huge’[15, 19]
