Criterion of Model Selection
Provided multiple different model candidates exist, the optimal model must somehow be judged.
Here we introduce Akaike Information Criterion (AIC) which was proposed
by Akaike in 1973 .
AIC is given by
whose minimum offers a proper estimate of the number of free parameters.
