Dear Yung-jin,

❝ [...] Now which criterion of the best fit should we use for the combo method? AIC or ARS? Looks like more people will vote for AIC, I guess. It should be implementable, too, with R. or both? Leave the option to the users to decide?


My personal choice is AIC, but with the full formula (see this message) to account for the varying number of data points.
Eventually the small sample AICc should be considered:
AICc=AIC + 2*p*(p+1)/(n-p-1)
    =AIC + 12/(n-3) with p=2

But with that n=3 is a problem (I have dealt with in an empirical manner).

But this is only an opinion. Therefore a choice from the user would be a good idea I think :yes:.

Regards,

Detlew
