g4: Goodreau's four node network as a "network" object

Description

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.

Usage

data(g4)

Details

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.
