Gibbs Random Fields Analysis
Description
Allows calculation on, and
sampling from Gibbs Random Fields, and more precisely general
homogeneous Potts model. The primary tool is the exact computation of
the intractable normalising constant for small rectangular lattices.
Beside the latter function, it contains method that give exact sample from the likelihood
for small enough rectangular lattices or approximate sample from the
likelihood using MCMC samplers for large lattices.
