Command auto arma with constant

[Herken]

Hi all,

I have two questions. I'm currently working on a program to automate the estimation of structural labour participation rates for different countries and age groups. I use Eviews 9, which offers the very convenient capture window. I want to use a command to automatically run arima models through various HP filtered series. If I do this manually, the capture window give me the following command:

ger_hp.autoarma(tform=log, select=hq, eqname=ger_eq) c

If i use this command and apply it, however, Eviews tells me c is not specified, so I have to delete the c in the command produced above. But here is the problem. Running the arima models with or without the constant term generate very different results. What is the proper command to generate automatic arima models with a constant term?

More in general,what settings can I use best in order to have the log kick in more heavilly. The forecasted HP series are rather steep and I want them to flatten more (i.e. diminishing returns).

Thanks a lot. Best,

Hugo Erken

You probably need to update your copy of EViews 9.

The correct command you want is probably:

Code: Select all

ger_hp.autoarma(tform=log, select=hq, eqname=ger_eq) ger_hp_f c
