Creating Seasonal Factor for multiple variables at once

Postby meganmao » Fri Aug 02, 2013 11:30 am

I'm trying to create a seasonal factor for multiple variables in one sweep. How can I do this?

Right. My bad!

So I have production data that is seasonal. I open the variable, go to Proc>Seasonal Adjustment>Census X12

My options are the following:

X11 Method: Multiplicative
Trend Filter (Henderson): Auto (X12 default)

Seasonal Filter: Auto (X12 default)

Component Series to Save
[checked] Final seasonal factors (_SF)


I want to do this for all the variables I have in one sweep

You'll have to write a program to do it.

How can I get started? I'm new to e-views programming but I've had programming experience in other statistical software.

I just can't find any code to look at that reflects the seasonal factor option. Or should I program based off the formula used to calculate the seasonal factor?

Look up the FOR loop in the Command and Programming reference.

Look up X12 in the SERIES section of the Object Reference.

Hi meganmao, did you work out how to do this? I'm trying to do the same thing.

You can use the GroupX12 add-in.

Thanks Nicolas,

I ended up running the seasonal adjustment manually and copying the command code (at the top of the seasonally adjusted series) into a programme so I can batch process the data into seasonally adjusted series - just if anyone looks this up and wants another option as to how to do this.
