EViews.com

I have series which is in monthly frequency.

In order to remove seasonality, I need to take 12th difference of it.

To take 12th difference, which Eviews command should I use?

Thank you.

Presumably you mean you want X-X(-12), which can be done with D(X,0,12).

If you want a 12th order difference, you would do D(X,12).
