How to solve the problem?

Dear all,
I want to change the data to do another topic, the output.mat is my data. But I got the following problem:
I don’t know how to match my data with the estimation part.
Final value of minus the log posterior (or likelihood):800.630805

POSTERIOR KERNEL OPTIMIZATION PROBLEM!
(minus) the hessian matrix at the “mode” is not positive definite!
=> posterior variance of the estimated parameters are not positive.
You should try to change the initial values of the parameters using
the estimated_params_init block, or use another optimization routine.
Warning: The results below are most likely wrong!

In dynare_estimation_1 (line 315)
In dynare_estimation (line 105)
In ERJ_est.driver (line 2450)
In dynare (line 293)

MODE CHECK

Fval obtained by the minimization routine (minus the posterior/likelihood)): 800.630805
mode_check:: could not solve model for parameter csih at value 0.627, error code: 3
Warning: Matrix is singular, close to singular or badly scaled. Results may be inaccurate. RCOND = NaN.
