False positive rate as a function of node degree (given 10000 observations) of shrinkage (blue), ridge (orange), and lasso (green) estimated partial correlations, and of pairwise correlations (red).

For each network, nodes were divided into 6 bins according to degree: 5 equally-sized bins, and a 6th bin containing the 50 nodes with the highest degree (i.e., the hubs in the hub networks). FPR is shown for each pairing of degree bins (e.g., eleventh pair (1,6) refers to edges between the nodes with lowest degrees and the nodes with highest degrees; rightmost pair (6,6) refers to edges between the nodes with highest degrees).
