Hi,

I am trying to estimate output gap with a very simple model, but i meet the following error:

Error using +
Matrix dimensions must agree.

Error in prior_posterior_statistics_core (line 274)
stock_filter_step_ahead(ii,IdObs,:,irun(4)) =
squeeze(stock_filter_step_ahead(ii,IdObs,:,irun(4)))...

Error in prior_posterior_statistics (line 241)
[fout] = prior_posterior_statistics_core(localVars,1,B,0);

Error in dynare_estimation_1 (line 520)
prior_posterior_statistics('posterior',dataset_,dataset_info);

Error in dynare_estimation (line 105)
dynare_estimation_1(var_list,dname);

Error in t (line 145)
oo_recursive_=dynare_estimation(var_list_);

Error in dynare (line 223)
evalin('base',fname) ;

Could anyone help me with this? Tanks a lot!

Best,
Elizaveta

Dear Elizaveta,

This is most likely a bug when we add back the trend in the filtered variables. Could you please try by replacing the file prior_posterior_statistics_core.m in the Matlab subfolder by the one attached to this post. Also I rewrote (and renamed) the mod file. Please confirm if these files fix the issue (we will then release the patch in 4.5.1).

Best,
Stéphane.

Dear Stéphane,

Running your example.mod file repeats the same error. New file solves the problem! Thanks a lot.

Best,
Elizaveta

Thanks Elizaveta. I need to check that the patch does not cause problems elsewhere... If not, it will be in 4.5.1 bug fix release (to be published next week).

Best,
Stéphane.
