question about examples in the User Guide

[learnbydoing]

Hi,

I download the codes for the examples in the User Guide.
(http://www.dynare.org/documentation-and ... s.zip/view)
When I ran fs2000ns.mod, I got the following error:
-------------------------error starts-------------------------------------
??? Undefined function or variable "F".

Error in ==> DiffuseKalmanSmoother1_Z at 136
Pstar(:,:,t+1) =
T*Pstar(:,:,t)*T'-T*Pstar(:,:,t)*Z'*Kinf(:,:,t)'-Kinf(:,:,t)*F*Kstar(:,:,t)'
+ QQ;

Error in ==> fs2000ns at 175

---------------------error ends---------------------------------------------------------------------

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,

[learnbydoing]

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

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

Best,

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
??? Error using ==> print_info at 39
Blanchard Kahn conditions are not satisfied: no stable equilibrium

Error in ==> initial_estimation_checks at 101
print_info(info, options_.noprint)

Error in ==> dynare_estimation_1 at 122
initial_estimation_checks(xparam1,gend,data,data_index,number_of_observations,no_more_missing_observations);

Error in ==> dynare_estimation at 62
dynare_estimation_1(var_list,varargin{:});

Error in ==> fs2000ns at 176
dynare_estimation(var_list_);

Error in ==> dynare at 132
evalin('base',fname) ;

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.

Hi, set lik_init=2 in the estimation command.

[lee]

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!

[SébastienVillemot]

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
