Figure 2. Probability density functions for the case of Gaussian-distributed connections.
A Distribution of the Gaussian variable 
B Distribution of the sum 
of two Gaussian-distributed variables. C Distribution of the absolute difference 
of two Gaussian-distributed variables. D Joint distribution of

E, F, G, H The same as A, B, C and D but with pruning 
In all the figures, Grey shaded area: histograms from simulations, Black lines and surfaces: theoretical results (see Eq. (19)–(25)).
