Evaluation of the goodness of fit of the different models, using the deviance information criterion (DIC)
| Model | Bayesian deviance D(E) | Posterior expectation of deviance E(D) | DIC |
|---|---|---|---|
| CAR model | 327.0638 | 406.4 | 487.0812 |
| CAR + non-irrigated arable land | 326.9857 | 405.5 | 484.0143 |
| CAR + log(non-irrigated arable land) | 327.5457 | 405.9 | 484.2543 |
| CAR + permanently irrigated land | 326.4911 | 405.3 | 484.1089 |
| CAR + log(permanently irrigated land) | 327.3546 | 405.9 | 484.4454 |
