Without additional hypotheses, conditional distributions {v i} are not generally compatible in this way. In this chapter, we will begin by describing a general family of conditional distributions called Gibbs specifications that are compatible without further conditions; Gibbs specifications are characterized by potentials. Their importance is enhanced by the Hammersley-Clifford theorem showing that Markov random fields are Gibbs random fields with local potentials. Besag’s auto-models are a particularly simple subclass of Markov random fields that are useful in spatial statistics.
