Thresholded precision matrix models. (Left) Edges produced by thresholding inverse of sample covariance matrix for the drug-free simulation. (Right) Edges produced by thresholding inverse of sample covariance matrix for the drug-bound simulation. Notice that the edges lack the kind of structure seen in Figures 2 and 3.
