g4 {ergm} | R Documentation |
This is an example thought of by Steve Goodreau. It is a directed
network of four nodes and five ties stored as a network
object.
It is interesting because the maximum likelihood estimator of the model with out degree 3 in it exists, but the maximum psuedolikelihood estimator does not.
