Distributions of similarity measures of epidemic simulations and their correlation. Frequency distributions of the Spearman’s rank correlation coefficient measured between arrival times on the two networks (a) and the Jaccard similarity index between the infection trees on the two networks (b). Each value of r_s and J(s) is computed over a statistical ensemble of 1000 simulations for a given outbreak seed s. Both histograms correspond to 329 binned values, one for each node of the commuting networks, and solid lines indicate the average of the distributions. Panel (c) shows the relationship between J(s) and r_s for each node of the networks.
