Hello, I have a large bipartite network with ~10^4 vertices of type I and ~10^6 vertices of type II. I fitted a nested blockmodel, hoping to identify communities of type I. Unfortunately, the detected communities (at the lowest level in the hierarchy) have a median size that is about twice as big as the empirical evidence suggests; (kind of reminding me of the resolution limit problem).
Is there a way to tune the sizes of the communities at the lowest level? I'm thinking - could forcing an extra hierarchy level help, or - adding in another (non-nested) simple block model at the lowest level? - Is it possible to reduce the penalty on the description length? Any ideas would be greatly appreciated... many thanks in advance!
