Distribution of Katz centrality Z-scores and the corresponding violin-plot. The distribution of Z-scores of Katz centralities has also heavy tails (left) and large values of Z are obtained dominantly for large values of Katz centrality, as shown by the violin-plot (right). The lateral width of the violins corresponds to the frequency of the distribution, with the mean given in the middle bar and outer bars corresponding to the standard deviation. The Katz centralities are shown on a logarithmic scale so that logK≈−3 corresponds to K≈0.1Kmax. Note the broadening of the distribution at logK>−3
