Graver basis for an undirected graph and its application to testing the beta model of random graphs

Ogawa, Mitsunori; Hara, Hisayuki; Takemura, Akimichi - In: Annals of the Institute of Statistical Mathematics 65 (2013) 1, pp. 191-212

In this paper, we give an explicit and algorithmic description of Graver basis for the toric ideal associated with a simple undirected graph and apply the basis for testing the beta model of random graphs by Markov chain Monte Carlo method. Copyright The Institute of Statistical Mathematics,...
