BYM, Besag, York and Molliè; D(E), deviance evaluated with respect to expected values; DIC, Deviance Information Criterion; E(D), expected deviance; pD, number of effective model parameters = E(D) – D(E); ZIP, zero‐inflated Poisson.

DIC = goodness‐of‐fit (E(D)) + model complexity (pD). Model selection criteria.
