Ms-sbvar

Dynare help (legacy posts)

Hi,
I am working with the unstable version of Dynare of 06/06/2011. I’m trying to estimate a Markov-switching BVAR using the command ms_sbvar. However, I’ve an error message:

“The expression to the left of the equals sign is not a valid target for an assignment.” The expression corresponds to the option “datafile”.

datafile is defined as an option in ms_sbvar.m
I don’t understand where is the problem!!!

Regards,

Tareq

Hi Tareq,

The command “ms_sbvar” no longer exists. The commands for running a MS-SBVAR model have changed.
You can find an example on the DynareWiki : dynare.org/DynareWiki/example_swz

Hope that helps you,

Stéphane

Many thanks,
It seems to work well. However, I have the following error when I use the command ms_forecast. Otherwise, all works well.

This is a bug and will be fixed. I’ll post a reply when it’s done.
