Hi everybody,
just a note that since last week or so there's a new contributed
function package on the gretl package server, namely MSVAR(.zip). As you
may guess from the name it does Markov-Switching VAR estimation.
(Frequentist, not Bayesian.)
I am very grateful to the author of the original Gauss code, Anders
Warne, that he continues to make his code available. Of course as the
package author I am responsible for any mistakes, but I haven't really
developed the algorithm or implementation per se.
The package is work in progress, but already comes with quite extensive
documentation. There are surely still a bunch of bugs in there, but in
principle it should hopefully be usable.
As explained in the documentation, this package can be driven by hansl
scripting (of course) but also via the GUI by attaching it to the menus
of the regular VAR model window during installation: So you would first
estimate a plain old VAR, and then go to the Edit window to find MSVAR
there and switch over to a switching model.
See some of you tomorrow at the virtual gretl workshop!
cheers
