Correlation coefficients versus network size. The averages and standard deviation of the associated R³ correlation coefficients have been computed and are plotted double logarithmically versus N. The straight line is the function AN^-2 with A = 135 and demonstrates that a decay of R³ can be explained by power -2 of the network size, which agrees well with the fact that () links have to be estimated from maximal N independent experiments. Networks of size N = 25 with average connectivity ⟨k⟩ = 5, N = 50 with ⟨k⟩ = 10, and N = 100 with ⟨k⟩ = 30 have been sampled and reconstructed for the assumed values of k = 1,..., N.
