There is an excellent two page crash course in
the documentation of the SVAR addon package.
I was wondering if Timmy was actually aware of the SVAR addon. I
have repeatedly heard from users who thought gretl could still only
deal with plain Choleski SVARs, and it wasn't quite clear to me from
his message to which part of gretl he was referring to.
In the documentation, it is stated that the SVEC
case will receive its own GUI in a future version of the SVAR
package however the authors recommend using the script
interface to access the full capabilities of the SVAR package.
As the second author of the SVAR addon I agree we should try to
deliver on the promise of some GUI wrapping in that area.
Dear Professors,
I am glad to inform you that Gretl is
gaining more ground in my country Nigeria nowadays.
However, I will like to make few suggestions to add to its
usefullness.
Thanks, that's good to hear!
I think there is a need to develop a special
GUI for SVECM and to support both long and short run
restrictions. If possible, it can be linked with the VECM
output in order to fetched its estimates from the
beta-alpha matrix.
see above
Moreover, I suggest that Gretl should be
developed to handle DSGE modeling.
Um, that's probably not going to happen any time soon. I'm glad that
also in the DSGE area there is a lot of open-source momentum
(keywords Dynare plus Julia or Python). Gretl doesn't have a
comparative advantage there, so I don't see the reason for making
gretl a DSGE tool.
What's more realistic in terms of missing features would be
something like Bayesian VARs which gretl doesn't have, either.
(Although personally I tend to be Bayesian only when I really have a
subjective prior, and often I --and I think the same goes for many
others-- don't. So IMHO another shrinkage/regularization estimator
would do just as well.)
cheers,
sven
