True 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).

<p>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). TPR is shown for each pairing of degree bins (e.g., sixteenth pair </p><p></p><p></p><p><mo stretchy="false">(</mo></p><p><mn>1</mn><mn>6</mn></p><mo stretchy="false">)</mo><p></p><p></p><p></p> refers to edges between the nodes with lowest degrees and the nodes with highest degrees; rightmost pair <p></p><p></p><p><mo stretchy="false">(</mo></p><p><mn>6</mn><mn>6</mn></p><mo stretchy="false">)</mo><p></p><p></p><p></p> refers to edges between the nodes with highest degrees).<p>
