Dear All,
I have run an open one country dsge model and it run for a while then end up as the following:
Log data density [Laplace approximation] is NaN.

Error using chol
Matrix must be positive definite.

I have attached my mod file and my data, is anyone who could kindly have a look?
i am currently in the final year of my phd, however, in my universities, I do not get much help in Dynare programming, hence, I wish some kind people could give some guidance, and I will be grateful.
Sincerely, Jesse

Sorry, but I cannot run the files, because of

Code: Select all

Blanchard Kahn conditions are not satisfied: indeterminacy

at the initial values.
