Hi all,

I am really frustrated by the following issue but didn't find answers in the forum, so I'm afraid I had to raise the frequently asked problem again. The setup is that I have two models, and want to compare the IRFs of each endogenous variables due to exo shocks. Say, model 1 and 2, both have endo variables y and c, exo shocks ea and em. So, the names of two models' variables are totally the same. Now, I want to plot two IRF figures, one for response of shock ea, another em.Each figure has two subfigures,one for response of y,another c.And each subfigure has two curves, one stands for IRF of model 1, another model 2. By learning from related posts in this forum, I just write the following code, but failed to run it out.

Code: Select all: dynare model1.mod load('model1_results.mat', 'oo_') irf1=oo_.irfs; save irf1 load irf1 dynare model2.mod load('model2_results.mat', 'oo_') irf2=oo_.irfs; save irf2 load irf2 ending_cell={'_ea','_em'}; for ii=1:length(ending_cell) HOR=1:1:40; var={'y','c'}; figure for jj=1:length(var) subplot(1,2,jj) eval(['irf1.' var{1,jj},ending_cell{1,ii}]); eval(['irf2.' var{1,jj},ending_cell{1,ii}]); hold on plot(HOR,[eval(['irf1.' var{1,jj},ending_cell{1,ii}])],'LineWidth',1,'-k',HOR,[eval(['irf2.' var{1,jj},ending_cell{1,ii}])],'LineWidth',1,'--r') title([var{1,jj}] ) end end

Matlab just stopped by warning"Undefined variable "irf1" or class "irf1.y_ea"."I guess the contents of irf1 are just overlapped by irf2, because all the variable names are the same among the two models. But I don't know how to get rid of the problem.Could anyone kindly give me another hand please?

Many thanks indeed.

GOODLUCK

I've tried dealing with this problem by reinstalling DYNARE4.40 exclusively in my personal computer under path C:, but with things unchanged. The error just displays as :

Undefined variable "irf1." or class "irf1.y_epsilon_A".

Error in plotting (line 37)
eval(['irf1.' var{1,jj},ending_cell{1,ii}]);

I am wondering whether things could be improved or fixed. I have no idea how to figure out the wrongs since I am also quite new to Matlab. So sorry that I have so many questions, yet I have to ask anyone has any idea?

Best,

GOODLUCK

You either need to load irf1 after the last call to Dynare or use the noclearall option.

Thank you very much, jpfeifer. I've done it.

Hi,GOODLUCK,

I meet the same question as you, but I still don't know how to plot them? Can you tell me how you do it? Thank you!

I d like to see an example solution as well

In particular I want to combine 2 irf-outputs from stoch_simul showing the IRFs for certain endogenous variables, for the same model (same endogenous variables, same shock, but different shocksizes) in one picture.

Hello!

I am very new to Matlab. I've spent so many days searching for the correct codes in combining plots. I tried also this code, but yes, it is with error. How to remove the error? Jpfeifer suggested to use a noclearall option or load irf1. How exactly to do the suggestion?

Thanks so much for the help in advance.

Please provide more information. Provide both the files and precise instructions on what you are trying to plot from the two mod-files.

Code: Select all: dynare Flexible_1.mod load('Flexible_1_results.mat', 'oo_') irf1=oo_.irfs; save irf_1 load irf_1 dynare Flexible_2.mod load('Flexible_2_results.mat', 'oo_') irf2=oo_.irfs; save irf_2 load irf_2 ending_cell={'_eps_A'}; for ii=1:length(ending_cell) HOR=1:1:20; var={'Welf'}; figure for jj=1:length(var) subplot(1,2,jj) eval(['IRF_1.' var{1,jj},ending_cell{1,ii}]); eval(['IRF_2.' var{1,jj},ending_cell{1,ii}]); load IRF_2 end end

he doen't work with me at all ! could you help me please

You must either load the first mat-file after the second call to Dynare or invoke the second call to Dynare with the

Code: Select all: noclearall

option. Otherwise, everything you do before

Code: Select all: dynare Flexible_2.mod

will be deleted.

Hi all

Please hint me in this code:

Code: Select all: dynare dr.mod load('dr_results.mat', 'oo_') irf1=oo_.irfs; save irf_1 load irf_1 dynare rd.mod noclearall load('rd_results.mat', 'oo_') irf2=oo_.irfs; save irf_2 load irf_2 ending_cell={'_epsr'}; for ii=1:length(ending_cell) HOR=1:1:40; var={'y','paii','gam'}; figure for jj=1:length(var) subplot(1,2,jj) eval(['irf1.' var{1,jj},ending_cell{1,ii}]); eval(['irf2.' var{1,jj},ending_cell{1,ii}]); hold on plot(HOR,[eval(['irf1.' var{1,jj},ending_cell{1,ii}])],'LineWidth',1,'-k',HOR,[eval(['irf2.' var{1,jj},ending_cell{1,ii}])],'LineWidth',1,'--r') title([var{1,jj}] ) end end

with this Error:

Code: Select all: ERROR: Untitled.mod: line 18, col 4: syntax error, unexpected EQUAL

Thank you!
Best wishes...

This is a problem with the mod-file Untitled.mod. The code you pasted is Matlab code and not Dynare code. Run this directly from Matlab.

Thank you very much, jpfeifer.
But after ruining all irf1 and irf2 separately, this error occurred again:

Code: Select all: Undefined variable "irf_1" or class "irf_1.y_epsr".

Thank you for your kindly reply.

Be more careful. If you define

Code: Select all: irf1

you cannot save

Code: Select all: irf_1

Also, you need to load the files after the last call to Dynare, not after you saved them.
