makegroup - what is the code to include % deviations?

[tzink]

From the GUI, it is possible to create a group that shows the results of the Active and Comparison scenarios, as well as either the absolute deviation between them or the % deviation (model object -> proc -> make group/table).

The group can also be created, including the deviations, within a program using

Code: Select all

modelname.makegroup(d) groupname @endog

from page 336 of the object reference

However, nothing is mentioned in the manual about including the % deviation instead of the absolute deviation. What is the option key to produce the % deviations?

Thanks

I'm not seeing what you refer to on p. 336. From the EViews 7 manual...

t= arg
(default= “level”)

Transformation type: “level” (display levels), “pch” (percent
change), “pcha” (display percent change - annual
rates), “pchy” (display 1-year percent change), “dif” (display
1-period differences), “dify” (display 1-year differences).

t= arg changes the output of the *entire* table. The option in the GUI, "% Deviations: Active from Compare" displays the *only* the deviation in percentage format, leaving the values of the actual variables unchanged. I want to achieve this using a program.

As for the manual reference, I was referring to the Object Reference, Chapter 1, p. 336, the makegroup function under the Model object.

Oh, I think I understand the question better now.

I haven't double checked this and I have to run and do some other things, but in a brief look at the code, it looks like the undocumented "R" option will do it for you. So replace the "D" with "R".

Perfect! (r) does the trick.

Thank you so much. I feel better knowing that it's undocumented too--I was getting worried I just couldn't operate the manual properly.

Should have been documented. Our apologies. I just checked and the documentation has been updated to reflect the option.

Thanks for your patience.
