## Figure 4.
Yeast gene co-expression module networks: the relationship between fundamental network
concepts . This figure demonstrates Observation 2. A reference line with intercept 0 and slope
1 has been added to each plot. The figures on the left (right) hand side depict network
concepts from the weighted (unweighted) network. A) and B) Centralization versus NetworkConcept(A - I) (y-axis) and their approximate CF-based analogs NetworkConcept_{CF,app }(x-axis)Centralization_{CF,app}; C) and D) Heterogeneity versus Heterogeneity_{CF,app}; E) and F) Intramodular clustering coefficients ClusterCoef_{i }versus ClusterCoef_{CF,app}. The analogous plots for Density are not presented since the fundamental network
concepts and their approximate CF-based analogs are almost identical and the dots
fall near the reference line with R^{2 }= 1 for both weighted and unweighted networks, and thus are omitted due to limited
space. In Figures A), B), C) and D), each dot corresponds to a module since these
network concepts summarize an entire network module. In Figure E) and F), each dot
corresponds to a node since these network concepts are node specific.
