Dynare forums

HI
I try to compute the root mean square error (RMSE) with dynare_sensitivity for a DSGE model but I encounter this error:


Operands to the || and && operators must be convertible to logical scalar values.
Error in initialize_dataset (line 35)
if isempty(nobs) || rows(rawdata)<nobs+first-1 %case 2: dataset has changed
Error in dynare_estimation_init (line 475)

Error in dynare_sensitivity (line 87)

Error in dsge (line 376)
dynare_sensitivity(options_gsa);
Error in dynare (line 180)

Thank you for your help!

Please upgrade to Dynare 4.5. I am getting a different error message there. The problem is that your dataset has 96 observation, but you set first_obs=10 and nobs=[90:96], meaning that you want to select 90 periods after first_obs, which would imply you want to use observation 10 to 99.

Hi
Thank you very much for your reply.
I have 96 observation. My goal is that have an in-sample forecast for the last two data and for 2 horizons and then do RMSE.I upgrade my dynare and I write this nobs=[85:86]

Estimation
(datafile=data_dsge,first_obs=10,prefilter=1,mh_nblocks=2,tex,mh_jscale=0.6,mh_replic=1500,mode_compute=6,lik_init=2,mh_drop=0.4,nodisplay,nograph,mode_check,nobs=[85:86],forecast=2)pi;

dynare_sensitivity (datafile=data_dsge,first_obs=10,pprior=0,ppost=1,prefilter=1,lik_only = 0,nobs=[85:86],rmse=1,var_rmse=(pi)) ;

But this error accrue:
Error using : (line 38)
dates::colon: In an expression like A:B, A and B must be dates objects!

Error in makedataset (line 252)
DynareDataset = DynareDataset(FIRSTOBS:lastobs);

Error in dsge (line 387)
dynare_sensitivity(options_gsa);
Error in dynare (line 228)

What should i exactly write for dynare_sensitivity?
Thanks for your reply.

Please provide the updated file

hi
this is my update file



thanks for your reply

In contrast to the

Code: Select all

estimation

command, the command

Code: Select all

dynare_sensitivity

does not take a vector-sized

Code: Select all

nobs

. Please use a scalar here.

Hi
As you said, I write nobs=85 (use a scalar) in dynare_sensitivity, but my program is still not working and this error occurs. I am confused.

Error using load
Unable to read file 'dsge/metropolis\dsge_data.mat'. No such file or directory.

Error in filt_mc_ (line 146)
load([DirectoryName filesep M_.fname '_data.mat']);

Error in dynare_sensitivity (line 416( filt_mc_(OutputDirectoryName,options_gsa,dataset_,dataset_info);

Error in dsge (line 387)
dynare_sensitivity(options_gsa);

Error in dynare (line 228)
evalin('base',fname) ;

Thanks for your reply.

There is an incompatibility of

Code: Select all

dynare_sensitivity

with estimation being run in recursive estimation. I will try to fix this soon. For now, try to run the code for each nobs separately.
