Model comparison by deviance information criteria (DIC) and the correlation between observed and predicted average daily gain of maternal Duroc pigs records (r y,ŷ) from an 8-fold cross-validation test, mean (SD) across folds
| AM | AM-IGE | AM-IGEFR | AM-IGEFF | AM-IGEFInt | AM-IGEOT | AM-IGEALL | |
|---|---|---|---|---|---|---|---|
| DIC | 1402.07 | 1348.69 | 1376.08 | 1338.59 | 1330.77 | 1304.74 | 1321.54 |
| r y,ŷ | 0.52 (0.12) | 0.53 (0.16) | 0.55 (0.09) | 0.52 (0.07) | 0.54 (0.05) | 0.56 (0.05) | 0.58 (0.04) |
AM=animal model; AM-IGE=animal model including classical indirect genetic effects; AM-IGEFR, AM-IGEFF, AM-IGEOT, AM-IGEFInt and AM-IGEALL=animal model including indirect genetic effects but using feeding rate, frequency, time, interval and overall index to define the specific degree of interaction between two individuals.
