regression with variable lags

[marcsean]

Hi,

I want to regress a variable on its lags. However, I want to choose the lags according to an criterion, so it should be variable until the criterion is not satisfied.

How does this work?

I suggest to run all possible specifications (all possible combinations of AR & MA terms, say, with max. AR order 15 and max. MA order 5). Store the criterion that you like in a matrix and then use a max operator.
