Dear all,

Could someone have a look at the mod-file in http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=3700

In estimation, it sets prefilter=1 and hence options_.noconstant gets set to 1.

dynare_estimation_1.m lines 1135 following in Dynare 4.2.5 and the current source read:

if options_.noconstant

        yf = zeros(n_varobs,gend);

else

if options_.prefilter == 1

            yf = atT(bayestopt_.mf,:)+repmat(bayestopt_.mean_varobs,1,gend);

elseif options_.loglinear == 1

            yf = atT(bayestopt_.mf,:)+repmat(log(ys(bayestopt_.mfys)),1,gend)+...

                 trend_coeff*[1:gend];

else

            yf = atT(bayestopt_.mf,:)+repmat(ys(bayestopt_.mfys),1,gend)+...

                 trend_coeff*[1:gend];

end

end

As a consequence, the filtered variables in yf, which are then plotted, are always 0. My guess is that this is a bug and the treatment of noconstant and prefilter is not consistent.

Moreover, I am not sure why we save atT to the results

eval(['oo_.SmoothedVariables.' deblank(M_.endo_names(i1,:)) ' = atT(i,:)'';']);

but plot yf, which is a transformation of atT.

Best,

Johannes
