As for the Svar I know that the user can choose the number of replications.
Instead, I would like to know what does gretl do when I ask to calculate
and plot Irfs from the model window without using the Svar pack!
Thank you!
Both the SVAR module and the C version use the simple bootstrap for
computing the confidence intervals for IRFs, as per Runkle (1987) "Vector
Autoregression and Reality", JBES.
I'll probably make the "bootstrap-after-bootstrap" method (Kilian 1998)
avalaible in the SVAR module soon, as an extra option.

This would be a nice feature. So far I am only aware of JMulti (Hall and
Efron percentiles ) and RATS which offer different procedures. I think
Eview has implemented only a standard MC-procedure.

I just uploaded a revised version of SVAR.gfn which contains the
bootstrap-after-bootstrap as an option.
Allin: how do I update the pdf file (everything is in CVS)?

Nice!
Allin: how do I update the pdf file (everything is in CVS)?
The required step here is to remake SVAR.zip and rsync it to
/home/frs/project/g/gr/gretl/addons/$VERSION/ on
<user>,gretl(a)frs.sourceforge.net , where $VERSION is the
minimum gretl version compatible with the package (in this
case 1.9.5). (If a new version directory should be needed it
must be created first, which can be done by sftp.)
I've now done this for current SVAR.

It is very useful to have this option available! Thanks very much!
I have seen that the version of svar is up dated on the server. What is the
code to compute that kind of bootstrap?
Thank you again!

All you have to do is setting the bundle element "biascorr" to 1 before
invoking SVAR_boot. For example:
<hansl>
abc = SVAR_setup("plain", Y, X, 4)
SVAR_estimate(&abc)
abc["biascorr"] = 1
SVAR_boot(&abc, 1000, 0.9)
</hansl>
It's in the pdf manual.
PLEASE treat this feature as experimental. I ran a few checks, but as we
all know, users are the best debuggers ;)
