example fs2000ns problem

[shengan28]

The example from chapter 6 of the user guide, fs2000ns.mod, does not work. What changes will make it work?
Here is the error message I get:

"Error using print_info (line 74)
Impossible to find the steady state. Either the model doesn't have a steady state, there are an
infinity of steady states, or the guess values are too far from the solution"

Please try the updated version at https://github.com/DynareTeam/dynare/blob/master/tests/fs2000/fs2000a.mod

Thanks Johannes, that works better, but I now get the error message:
"Error using eval
Undefined function or variable 'P_obs'. "

That does not make sense since the variable P_obs is defined in the Model block, and Dynare does not have a problem with the variable Y_obs.

Where does the problem occur. I cannot replicate the issue in 4.4.3. Please post the full error message.

You are missing the dataset file fsdat_simul.m. It can be found e.g. here https://github.com/DynareTeam/dynare/blob/master/tests/fs2000/fsdat_simul.m

Thanks again for the post. I did have the old fsdat_simul.m file, so I replaced it with the new one. That seems to work better, but I still have a few error messages. Here they are. Thanks again for your help.

Why are you using the fs2000ns again. The file I linked to has a steady_state_model block so that the error message cannot appear in this case.
