Dynare forums

Hi everyone,

I am trying to obtain IRFs from the mod-file in the Dynare User guide by Mancini, in Chapter 6. To be specific, I have added the option 'bayesian_irf' in the options of the estimaton command:

estimation(bayesian_irf, datafile=EMU_data,mh_nblocks=2, loglinear, mode_compute=4, mh_replic=3000, mh_drop=0.45,mh_jscale=0.65, nobs=61);

However, when I run the file I get the following error message:

??? Error using ==> irf
Too many input arguments.

Error in ==> PosteriorIRF at 181
y=irf(dr,SS(M_.exo_names_orig_ord,i), options_.irf, options_.drop,options_.replic,options_.order);

Error in ==> dynare_estimation at 943
PosteriorIRF('posterior');

Error in ==> Chapter_3_DSGE at 170
dynare_estimation(var_list_);

Error in ==> dynare at 102
evalin('base',fname) ;

Please find the complete mod-file below.

Thank you,
Fontana

Most probably there is a problem with the path of the Econometrics Toolbox, see http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=2693

Thank you jpfeifer. That is what I thought as well, so I copied the mod-file into my original Dnyare folder (i.e. where I installed it, don't ask why I am using two folders, it is a long story), but then I get this error message:

??? Error using ==> chol

Best,

I just downloaded and reinstalled the recent version of Dynare, and now it works. I assume it had something to do with the Eco-Toolbox and the path, as you had suggested.

Thank you so much for your help.
