Dear all:
I have a time series data in gretl. Can I convert it to x-12-arima spec file?
Because it can not creat X-12-ARIMA spec file with excel.
I do not know how to creat X-12-ARIMA spec when I have data in excel,
(maybe convert excel to dat. but I dont know how to do this)
So I want to creat spec through gretl.
Thanks a lot
