Fig. 3From: Graph reconstruction using covariance-based methodsSelecting a hard-threshold based on the R 2 and the mean degree values which are plotted versus hard-thresholding values. The hard-thresholded values starting from 0.3 give rise to scale-free topology except 0.7 and higher. The corresponding mean degree values are relatively low indicating a sparsity of the underlying graph. The numbers in the plot represent different thresholds which are plotted for illustration purposesBack to article page
