Hello, everybody, when I estimated my model, dynare warn me "The rank condition ISN'T verified!" and can't finish the whole estimation. I attached the errors information, my mod file and data file here. Thank you for your help.

The rank condition ISN'T verified!

Loading 55 observations from obs_data.m

PARAMETER INITIALIZATION: Some standard deviations of shocks of the calibrated model are 0 and
PARAMETER INITIALIZATION: violate the inverse gamma prior. They will instead be initialized with the prior mean.
Error in computing likelihood for initial parameter values

ESTIMATION_CHECKS: There was an error in computing the likelihood for initial parameter values.
ESTIMATION_CHECKS: You should try using the calibrated version of the model as starting values. To do
ESTIMATION_CHECKS: this, add an empty estimated_params_init-block with use_calibration option immediately before the estimation
ESTIMATION_CHECKS: command (and after the estimated_params-block so that it does not get overwritten):

Before going to estimation, make sure your model runs with stoch_simul. You most probably have timing errors in your model. I am pretty sure your timing of capital for example violated Dynare's stock at the end of period timing convention.

Dear jpfeifer, thanks a lot for your answer. I have solved the problem. Now I have another question, that is, how can get the IRF values of variables? because according the original producer, only output the figure of IRFs.
