Table 3.
Akaike Information Criterion (AIC) values indicating goodness-of-fit for each exposure model examined.
Child-parent separation trajectories | Ranka | AIC | Additional d.f.b |
---|---|---|---|
Child-parent separation status at birth | 7 | 138014 | 3 |
Child-parent separation status at 15th birthday | 5 | 132557 | 3 |
Age at first child-parent separation | 1 | 130273 | 48 |
Duration of child-parent separation in years | 2 | 130374 | 45 |
Duration of familial cohesion in years | 4 | 132238 | 15 |
Total no. of changes in child-parent separation status | 6 | 132922 | 5 |
Array of specific child-parent separation trajectories | 3 | 130740 | 24 |
The AIC values are ranked smallest to largest; the smaller the AIC value, the better the model fit.
The AIC value for the ‘initial’ model fit included only the adjustment variables (with 232 degrees of freedom, d.f.) and did not include a child-parent separation exposure variable. This column indicates the additional degrees of freedom in the model according to each of the seven exposure variables added separately.
