Node degree ( k ) distributions for the MA, NI coexpression networks. (A) The connectivity distribution [f(k) × k] is shown for the MA (blue diamonds) and NI (red squares) coexpression networks. The inset of the panel shows the same plot with the axes in log10-log10 scale. (B-C) Comparison of exponential versus power-law curve fitting to the node degree distributions, shown without the tails. The best fitting power-law (dashed lines) and exponential (solid lines) trends are shown for each distribution. (B) Node degree distributions are shown in log10-log10 scale where a power-law distribution should follow a straight line. (C) Distributions are shown in semi-log10 scale where an exponential distribution should follow a straight line. The data are better fit by an exponential distribution.
