Dynare forums

Hi, I am a PHD student at French Polynesia University trying to learn Dynare

to run RBC_Est.mod (attached), you need simuldataRBC.m
this file should be generated by RBC_DataGen.mod (attached)
When you run it, dynare gives the following error messages:
Starting Dynare (version 4.4.3).
Starting preprocessing of the model file ...
[color=#0000FF]ERROR: RBC_DataGen.mod: line 205, cols 32-46: syntax error, unexpected NAME
error: DYNARE: preprocessing failed
error: called from:
error: c:\dynare\4.4.3\matlab\dynare.m at line 174, column 5[/color]

this problem has already reported in the forum:
viewtopic.php?f=4&t=4209
viewtopic.php?f=1&t=1477 : this reply gives corrected simuldataRBC.m (attached) and RBC_DataGen.mod which is taken back in Dynare Userguide (the code is the same)

So, you cannot have data generated for RBC_Est.mod
Let us try the simuldataRBC.m given by the 1477/reply and run RBC_Est.mod, you will have the following error messages:

Starting Dynare (version 4.4.3).

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

So, I checked the content of simuldataRBC.m, it is c=[data] and not y which appears in line 17 varobs y;
replacing c by y does not work neither

Many thanks for somebody to help me

Unfortunately, this is a problem with Octave. Please use the attached file where I replaced the gamma by a normal prior.

Many thanks for your help, it worked well with this substitution by normal distribution

I tried to use RBC_Est.mod (attached) with my own data file (seasonally adjusted GDP in data.m attached)
it produced the following errors:

You did not declare endogenous variables after the estimation/calib_smoother command.
Forecasts will be computed for the 9 endogenous variables of
your model, this can be very long....


Choose one of the following options:

[1] Consider all the endogenous variables.
[2] Consider all the observed endogenous variables.
[3] Stop Dynare and change the mod file.

options [default is 1] = 2

I got the same errors with y=GDP in trend cycle,

Must I use detrended GDP ( = raw data - trend) ?

thanks

My guess is that your Octave has trouble with you using a comma as the decimal separator in the data set. Use a fullstop instead.

again, many thanks ! your guess is very nice, all works with full stop !
