Geodesic distance counts #64

Geodesic distance distribution count exceeds total possible dyad counts (e.g., for faux.mesa.high: choose(205, 2) = 20910)

This may be how SNA calculates geodesics. From ?geodist:

geodist (without loss of generality) treats all paths as directed, a fact which should be kept in mind when interpreting geodist output.

This doesn't explicitly say it treats all networks as directed, but it suggests that.

I'll see if I can engage Carter. Calling

@CarterButts

  1. does this mean geodist treats ties in undirected graphs as directed mutuals?
  2. is the result that all geodesics in undirected graphs are counted twice (once for i->j, and once for j->i)
  3. is there a reason this is the preferred behavior for undirected graphs?

@martinamorris : is this closed?
