RBC_Est.mod Errors

Postby dale » Fri Mar 27, 2015 2:03 am

Hi, think this topic had been dealt many times but face a new error message like below
(already set the mean and variance of psi with gamma.pdf as 1.75, 0.1 respectively)
Do we miss something in last estimation command of RBC_Est.mod?

========================

You did not declare endogenous variables after the estimation/calib_smoother command.

Using Dynare 4.4.3 and Octave 3.8.2 versions now.
It seems that errors has something to do in part with GNU GUI..

If I add graphics_toolkit("gnuplot"); then more graphs come out but a long warning message show up like below

Please provide all files to replicate the issue in a zip or rar-file

Dear Pfeifer,

Attached pls find the files. The RBC_Est.mod is the same as one presented in DYNARE User Guide(2007-208) pp54.

I was unable to replicate any problems with Matlab. I will have to try it with Octave. Which Dynare version are you using?

It seems there is no reason to worry. Octave seems to have a hard time computing the moments of the prior distribution specified, but finally succeeds. After that, everything runs as expected-

Thanks a lot!
However still not sure if I got all the ouputs and the graphs right and correctly from the estimation. For example, the 4th graph of comparing historical and smoothed values look totally overlapped and same. I think it should be different but something might have gone wrong. I would appreciate if you can send me all outputs and graphs estimated with Matlab or Octave.

For observed variables, the smoothed and historical values must be the same (unless there is measurement error). The results look OK.
