Hello,

I have an error when I do shock decomposition using Dynare 4.4.3 and Dynare 4.3.2. I even get the error using an example file from F. Collard

Really appreciate some help.

This is the error and see attached file:

Error using evaluate_smoother
Too many output arguments.

Error in shock_decomposition (line 67)
[oo,Smoothed_Variables_deviation_from_mean] = evaluate_smoother(parameter_set,varlist);

Error in example1 (line 168)
oo_ = shock_decomposition(M_,oo_,options_,var_list_);

Error in dynare (line 180)
evalin('base',fname) ;

The datafile is missing. Have you tried the unstable version?

Hi jpfeifer,

Thanks for the response. I'm using a calibrated model, I shouldn't be using any data, right? The file "example1_calib_shock_decomp_data" is an empty mat file where the results are going to be stored. Is that right?

I tried using unstable version but still got an error:

Error using : (line 62)
dates::colon: init must precede !

Error in dseries (line 137)
ts.dates = init:init+(nobs(ts)-1);

Error in makedataset (line 103)

Error in example1 (line 179)

Error in dynare (line 223)

I'm using Matlab_R2016a on a Mac OS X El Capitan
Thank you again,

Of course you need a datafile. shock_decomposition conducts a historical decomposition of the variables' deviations from their mean in terms of shocks that drove them. How are you supposed to do this historical decomposition without a history of data? The datafile at https://github.com/DynareTeam/dynare/raw/master/tests/shock_decomposition/example1_calib_shock_decomp_data.mat is not empty and should work with the mod-file at https://github.com/DynareTeam/dynare/blob/master/tests/shock_decomposition/example1_calib_shock_decomp.mod
