Bug in assortativity for undirected graphs
I use graph-tool extensively for large graphs to the order of 100 million edges. Now my assortativity coefficient comes out to be > 1, which is not possible. The standard deviation comes out to be in the order of 1000's. Now my problem is that why is assortativity not being calculated exactly since it is O(E) algorithm. And even if it is sampled, it should not be > 1 atleast. Could be that I am doing something stupid. Please shed some light.
