Figure 6.

Performance of different GGM approaches. (a) ROC curves and (b) the proportion of true-positive edges as a function of the number of selected edges for the different graphical modeling strategies. Black line, the standard GGM; red line, frequentist modified GGM approach; blue line, latent random graph modified GGM approach; green line, pairwise correlation. Sparse networks with fewer edges as nodes (γ = 2.5) are represented in the left column, networks with approximately as many edges as nodes (γ = 1.5) are represented in the middle column, and networks with approximately twice as many edges as nodes (γ = 0.5) are in the right column.
