Comparison of the absolute pairwise correlation coefficients and the modified GGM approaches. (a) Selected edges in the frequentist modified GGM approach (0 and 1 denote absent and present edges respectively). (b) θ-values in the latent random graph approach. (c) θ-values after attaching 795 genes from other pathways.
