Dear Gretl users,

I have two questions concerning VARs:

1. Is there any built in function in gretl for historical forecast error
variance decompositions?

Not at the moment, but addinbg this to the SVAR package has been on my to-do list for a long time. I'll see what I can do in the next few days.

Attention everyone (esp developers): a new version of the SVAR package which includes historical decomposition is in CVS. Before we give it official status, I'd like people to test it if possible, especially the new features (see section 4 of the accompaying pdf document). The example directory contains a "BlQuah_hd.inp" file with an example, but clearly if people could try out the new stuff with their own data would be best.

Thanks!

I've received no feedback whatsoever on the new features, which can either be a very good sign or a very bad one.

The new version of the SVAR addon is now available to everybody using a CVS version of gretl or a windows snapshot. In order to grab it, you

1) go to the help menu, select "check for addons", and update SVAR
2) in the "examples" subdir, you should now find a "BlQuah_hd.inp" file,
   which exemplifies historical decomposition using the famous
   Blanchard-Quah dataset
3) the relevant info is now section 4 of the SVAR.pdf file, which is in
   the usual place.

Please test!
