Data frequency conversion: how to convert quarterly y-o-y data to plain q-o-q change format

Postby aartemenkov » Fri Jun 11, 2021 12:41 am

Dear forum participants,
I have a question not addressed by data frequency conversion help guidances in E-views. I have a data series reflecting y-o-y change in quarterly format (e.g. how GDP changed in the year to Q32020 compared to the year to Q3in 2019) I want to have these data converted into a plain q-o-q form, i.e. to reflect how this quarter's GDP changed compared to the previous quarter's.
Probably others have encountered a same problem and maybe some of you now the routines for that.
Will be most gratefull for any help.
Regards,
Andrey Artemenkov

Hi Andrey

This has actulay nothing to do with Eviews, instead, it is a mathematical problem.

Unfortunately, this is not possible because you do not have any information about the actual level of the variable for each quarter.

Regards Johan
