Bayesian Estimation crash

I have make some adjustments to the fs2000.mod file to include a Taylor rule and I made some adjustments to the bank's balance sheet. The stochastic shock works just fine. But my Bayesian estimation causes dynare to crash. :x The error message is
The loglinearization of the model cannot be performed, because the steady state is not strictly
positive.
Also, dynare tells me to try adding
an empty estimated_params_init-block with use_calibration option immediately before the estimation command
. Would this work? Is there an example of what this means?

Please advise.
Thanks

Add
estimated_params_init(use_calibration);
end;

The problem is that without explicitly provided starting values, estimation will start at the prior means. But at the prior mean, the steady state of
Code: Select all
gap

becomes negative, giving rise to the reported error message. But given that you have a running calibrated version of the model, you can use the
Code: Select all
use_calibration
option.
