Unraveling Spurious Properties of Interaction Networks with Tailored Random Networks

Figure 4

Simulation results for the degree distribution.

(a–c) Degree distributions estimated for realizations of networks derived from time series () via thresholding using various edge densities and for selected values of the size of the moving average and of the length of time series. The symbol legend in (a) also holds for (b) and (c). (d) Dependence of correlation () between node degrees and power content in the lower frequency range on the size of the moving average. Mean values of correlations obtained for realizations of networks for each value of are shown as crosses and standard deviations as error bars. Stars indicate significant differences in comparison to (Bonferroni corrected pair-wise Wilcoxon rank sum tests for equal medians, ). Lines are for eye-guidance only.
