Exchange with GAMS / .gdx files

Postby T8SCH » Tue Jun 14, 2016 1:26 am

GAMS is a powerful optimization software, but GAMS is not very convenient for data analysis.
Our databases and econometric forecasts are handled with EViews, meaning that we actually use EViews before and after running our CGE model in GAMS, and thereby transfer data from .wf1 to .xls and then to .gdx and vice versa (and unfortunately writing big datasets in an Excel file is very slow in GAMS).

Some useful EViews features would be to

    1. read .gdx files (a binary file format) and save results in an EViews workfile;
    2. write .gdx files from an EViews workfile or database;
    3. execute GAMS programs from within EViews.

Some tools exist for Matlab, R or Troll users, but I'm sure you can make better than all of them! ;)

Hi

Im curious.
Why do you not use Eviews to simulate your model? What type of functionality does GAMS have that is not a part of Eviews?
