This is something that can be easily from by asking the dear old google...

But in general, there are various different model selection techniques and
using some sort of Information Criterion is just one of them.  Personally I
tend to go for BIC, as AIC does not take the number of observations into
account.  Having said that when I do model selection, I would do a few
different *IC's just to be sure...
