X11 Seasonal adjustment on a "GROUP" of 10 series

[Tashfin]

Hi,

I can run an Seasonal Adjusment X11 procedure on a single series using the PROC -Seasonal adjusment Option on the EVIEW menu - However if I "GROUP" say 10 similar series and wish to run the X11 procedure on all of them at the same time, I cannot see the "PROC- Seasonal adjustment" Option appearing - anyone suggest how it would be possible to do this.

thanks.

You'll have to write a program that loops through the series and performs X11 on each of them one at a time.

Hi there,

I am struggling with seasonality adjustment of panel data.
I have a panel data file uploaded to EViews. Its structure is the following:
variable1 variable 2 ... etc
year1 quarter1 country1
year1 quarter2 country1
year1 quarter3 country1
year1 quarter4 country1
year2 quarter1 country1
....
year1 quarter1 country2
year1 quarter2 country2
year1 quarter3 country2
year1 quarter4 country2
year2 quarter1 country2

Is there a way to make a seasonal adjustment of my data in EViews?

EViews doesn't offer seasonal adjustment of panel data. You'd have to convert your panel into a pool.

Thanks, Gareth!

Can EViews convert my panel into pool, adjust for seasonality and then convert back into panel, if my initial excel file was in the format I showed before?

p.s. I am using EViews8

[EViews Gareth]

Yes. It is called unstacking the workfile, and there is documentation of it in User Guide I
