Concerning the option of "mode_check"

[blablur21]

Hi

I am new to DSGE model using dynare. There seems to be problem when estimating model using the option of "mode_check."
Following results are present in the window which seems to be a steady state problem.

First, what does the following error sign exactly mean? and is there any way to solve this problem ? (especially, with respect to the steady state)

Secondly, With this case, then do I have to give up final results, that is, parameter value of the posterior (if not "mode_check" in the estimation, mean parameter value is relatively plausible and satisfactory)

Finally, I am not exactly aware what is "smoothing variable" and why it is necessary. I couldn't find it anywhere in the material including dynare manual and user guide.

Any help would be a good to me.

STEADY: The Jacobian contains Inf or NaN. The problem arises from:

STEADY: Derivative of Equation 43 with respect to Variable data_CC (initial value of data_CC: 0.149266)
STEADY: Derivative of Equation 43 with respect to Variable data_IH (initial value of data_IH: 0.0393589)
STEADY: Derivative of Equation 43 with respect to Variable data_IK (initial value of data_IK: 0.347662)

STEADY: The problem most often occurs, because a variable with
STEADY: exponent smaller than 1 has been initialized to 0. Taking the derivative
STEADY: and evaluating it at the steady state then results in a division by 0.

Could you please provide me with the files to replicate this issue? This seems to be a bug.
