| The chi-square coding test for nested Markov random field hypotheses |
|
|
| Cécile Hardouin1Xavier Guyon1 |
|
|
| Let Y be a Markov random foeld on S parametrized via its local conditional specifications. We study consistency of coding and pseudo-likelihood estimators. Then we obtain conditional asymptotic normality for the coding estimator and deduce that the difference of coding statistic for two nested hypotheses is, unconditionally, a chi-square. For these results, we do not need regularity of the lattice, translation invariance for the specification or weak dependence for the field. |
