I need to justify when you call a network dense and need a cite or "expert" opinion...
I have two networks (venture capitalists, afflilation network linked by funding companies together although only retained the ties between venture capital firms, similiar to actor/movie network with essentially the same Log transformation of frequency of in degree plot shape including the slight left drop off), one component each. In addition the biger network has 17isolates and 4 dyad pairs not connected to the main component (too bad was hoping for more components as this trashed a few hypotheses), and the smaller network has fewer isolates, 3 dyad pairs and one pair of 4 not connected to the main componet.
Removing the isolates and unconnected dyads/group of 4 here is the network:
In the first one I have 277 nodes, 31,087 ties and the possible number of ties would be 76,452 so that dividing ties have by ties total I get 0.4066 for the network density.
In the second network I have 191 nodes, 13,485 ties, 36,290 possible ties and so get a density of 0.3716.
The drawing of each network looks like a tightly wound ball of yarn without much of a periphery although the smaller network has a bit more periphery but still the bulk of it looks like a tight ball.
I need to make a statement about whether these networks are dense or not and justify it with a reference that gives when you can call something dense or an expert who I can cite...
