Statistics of the networks by the HD and NHD models and the yeast PIN

The number in parentheses represents the standard deviation calculated from 100 networks generated by simulations. ?, the same as above.a.Parameters used in the simulations. See Materials and Methods.b.The number of homologous pairs. Two nodes are defined to be homologous when the evolutionary distance between the two nodes is dT or less.c.The number of interactions between homologous proteins.d.The average degree.e.The average cluster coefficient.f.The average shortest path length.g.The yeast PIN without self-interactions.h.A random network that has the same k> and N as those in the yeast PIN, where N is the number of nodes (3,891) in the yeast PIN. The values of C> and L> were calculated using the formulae K>/N and logN/logk>, respectively.
