Dear R users,
Assume I have three models with the following AIC values:
model AIC df
model1 -10 2
model2 -12 5
model3 -11 2
Obviously, model2 would be preferred, but it "wastes" 5 df compared to the
other models.
Would it be allowed to select model3 instead, simply because it uses up less df and the delta-AIC
between model2 and model3 is just 1?
Many thanks for any suggestions/comments!
Best wishes
Christoph
