Table 2. Deviance information criterion (DIC) for the three models tested.

(a) No covariates (i.e. null model where all individuals have the same hazard rate); (b) proportional hazards (where mortality differs proportionally between orphan classes); (c) covariates modifying all Siler mortality parameters (where each orphan class has a different age-specific mortality), for each sex (98 females and 102 males). The delta DIC shows the difference in DIC from the model with lowest DIC.
