Transformations within Eviews (QoQ, 3M Diff)

[athens82]

Hello.

I was trying to figure out if there's an way to compute a 3 month simple difference of a series (as well as a QoQ percent change) directly within an Eviews regression - using monthly data. I understand I can do this for a 1 period difference (using d(series)) or year-over-year percent change (using@pcy(series)) directly in the command line or program (i.e ls Y c d(x1) @pcy(x2)). I would just like to transform x1 into a three month difference and x2 in a quarter-over-quarter percent change in this example

Pls advise.

Thanks

There's always the manual way: X-X(-3)

That's true. Just wanted to make sure there wasn't a specific argument already built into Eviews that I was missing. Thanks for your assistance.
