Third order derivatives of external functions ERROR

Stochastic simulations
1

Hi all,

I want to simulate a model with a third order perturbation. I use an external function from Matlab to get the lognormal cdf. The problem is that Dynare doesn’t go through saying ‘‘ERROR: third order derivatives of external functions are not implemented’’

Any ideas on how can I solve this?

Regards

You cannot solve this, because this feature is not supported by Dynare yet: github.com/DynareTeam/dynare/issues/300

Thank you Johannes.

Hi,

Can I somehow provide the numerical value for the 3rd order derivative using a Matlab function in Dynare?

Unfortunately, that is not possible.
