Estimation of User Guide example model

[ger163609]

Hello!
I just tried to estimate the RBC model from the Dynare user guide. For some reason it doesn't work but I can't figure out where the bug lies. If someone of you could help me out, I would appreciate it a lot!

Always I try to run the model the following error message shows up:

>> dynare RBC_est

Does it have to do with the version of Dynare? I have tried several versions, but the problem is still there.

It would be great if anyone out there could give me a hint

1. Your Excel-file seems broken.
2. The file contains 120 observations, but you tell Dynare to load 500 observations and drop 200. That won't work.

I attached a running version.

Hey!
Thanks a lot for your help, I appreciate it a lot! I am sorry for replying that late but I've been offline the last days.

The datafile actually seemed to be broken anyhow. Now Dynare accepts it and is able to run the MCMC simulations; Though, the posteriors are only displayed as tables and not as graphs. Additionaly, some errors show up which are plugged in below. Do you have the same problem in your simulation? Thank you again for your contributions!

Hi, what's wrong with the files attached (Rbc_Est.zip) ? I have also tried the unstable version. Is there another running version ? Thanks

[jpfeifer]

What is the problem you face?

[eta]

The same errors mentioned by ger163609 in his last post.

[jpfeifer]

Sorry, but that mod-file does not work. Apparently, it has been broken from the start. You cannot estimate all those parameters when only observing output. Some of the parameters are not identified. Why do you need this file?

[eta]

I was just looking for a simple example of estimation. Thanks.

any of you guys have a running version of simple model?
