Hi,
I download the codes for the examples in the User Guide.
([dynare.org/documentation-and … s.zip/view](http://www.dynare.org/documentation-and-support/user-guide/models.zip/view))
When I ran fs2000ns.mod, I got the following error:
-------------------------error starts-------------------------------------
??? Undefined function or variable “F”.

How to fix it? Thanks.

This is a bug in Dynare which was fixed in one of the latest releases. Please upgrade to 4.1.3.
Best,

seems like I am using dynare whose version is 4.1.3. My matlab is 2008b and 2010b.

Sorry you’re right, the bug is fixed in unstable but not in Dynare 4.1.3.
Until a new stable version is released, please use the attached version of the file “DiffuseKalmanSmoother1\_Z.m” that you should put in the “matlab” subdirectory of your Dynare installation.

Dear Stephan
I use matlab7.10.0,Dynare 2011-06-01 version,but the fs2000ns code don’t work. The wrong is as fowllow:
Error in computing likelihood for initial parameter values

Dear Stephan,
I also found the same error as Lee found (Jun 03, 2011 5:34pm) when run fs2000ns code. Would it be possible to explain why this happened, please?
Many thanks.
Wira

Hi, set lik\_init=2 in the estimation command.

Thank you very much for your replying.But I add the option ‘diffuse\_filter’, the code also work.Is there difference between the option diffuse\_filter and lik\_init? which is better to the unstable model?
Many thanks in advance!

Actually the “diffuse\_filter” option was missing in this example from the User Guide. This will be fixed in the next draft of the guide.
Thanks
