Model parameters in absence or presence of covariates for the spatial models and their non-spatial counterparts.

CI, credible interval; DIC, deviance information criterion (a measure of model fit; a lower DIC indicates a better fit).
σ is the location-specific unexplained variance.
ρ is the decay parameter. The range (range = 3/ρ) is the distance at which the spatial correlation becomes less than 5%.
