Edge confidence estimation for the ALARM network The horizontal axis is the frequency threshold above which an edge is said to be present. The left-hand vertical axis is the number of edges. The solid blue line is the total number of edges. The faint purple lines are the number of edges found for each of 60 independent permuted data sets. The solid red line is the average number of edges found in the permuted data sets. The solid yellow line is the difference between the total number of edges and the average number of edges in the permuted datasets. The right-hand vertical axis is the confidence that an edge is real. The solid green line is the confidence associated with an edge found at the threshold concerned.
