The stats should have been close to the previous ones.

I can introduce additional stats. But then I should call them differently. I do not say that average path length is not interesting. But selling it to users as "closeness" is like calculating means and then labelling it "variance". I do not mean to offend anyone. I am simply emphasizing potential issues that may arise from altering the definition of narrowly defined statistical measures.

Well, I have been living my live thinking that the closeness is the same average path length. Wikipedia says the same at https://en.wikipedia.org/wiki/Centrality In a connected graph, the normalized closeness centrality (or closeness) of a node is the average length of the shortest path between the node and all other nodes in the graph. -- Cheers, Thomas Krichel http://openlib.org/home/krichel skype:thomaskrichel
As far as I understand it, the normalized closeness is "N / (sum d)" or "(N - 1) / (sum d)". Whereas average path length is "(sum d) / N". See https://en.wikipedia.org/wiki/Closeness_centrality or https://neo4j.com/docs/graph-algorithms/current/labs-algorithms/closeness-ce....
