Fig. 6From: Testing biological network motif significance with exponential random graph modelsGoodness-of-fit plots for the triad census of (a) the Alon E. coli regulatory network, Model 1 (Table 6), and (b) the Alon yeast regulatory network, Model 1 (Table 7). The observed triad counts are plotted in red with the triad counts of 100 simulated networks plotted as black boxplots. Because the triad counts (y-axis) are on a log scale, values of zero are omitted (observed zero counts shown as a red point on the bottom of the graph). In (a), for triad census class 030C (cyclic triad), the “box plot” consisting of a single median line for the simulated count represents a single (out of 100 simulations) occurrence of a nonzero count (of 1) for 030CBack to article page
