Table 3. Comparing full covariates model with the model excluding unrealistic relationships.
| Capelin age | MAR model | Log-likelihood | # parameters | AIC |
|---|---|---|---|---|
| 1 | Full relationships | -247.7 | 25 | 545.3 |
| Excluding relationships fishes → temperature | -246.5 | 20 | 535.0 | |
| 2 | Full relationships | -253.8 | 50 | 607.5 |
| Excluding relationship fishes → temperature | -249.2 | 42 | 583.6 | |
| 3 | Full relationships | -235.6 | 25 | 520.6 |
| Excluding relationships fishes → temperature | -235.5 | 21 | 513.0 |
The unrealistic relationships mean the flow from biological factor to environmental factor such as fishes → temperature.
