Dear professors,
I’m a new for dynare and I need help. The attachment is my program and data, I donot know why this error happens. deleverage1 and deleverage0425news are the right datafile and mod.
It seems that when I try an estimate one of the parameters in particular I generate the following error message:
Log data density [Laplace approximation] is NaN.
Error using chol
Matrix must be positive definite with real diagonal.
Error in posterior_sampler_initialization (line 84)

I hope my questions make sense, and any guidance on what could be causing this error would be much appreciated.
Kind regards
