Dear Mustafa,
There are several means by which to obtain model comparisons via
functions of the
model likelihood or information criteria with Stata time series. I will
proffer a simple one here.
First, install estout from the ssc archive
with the ssc install estout command.
Then type: sysuse turksales
tsset t
eststo: arima turksales, ar(1)
eststo: arima turksales, ar(1/2)
To obtain your model comparisons with AIC and BIC, then
type:
est stats _all
I hope this helps,
Robert Yaffee
