How to run fourth-order and higher approximations

Stochastic simulations
1

Hi all,

I am fairly new to Dynare so I imagine this is a pretty basic question. I would like to run a fourth order approximation and I am not sure how to. I know that the stoch_simul command allows orders 1-3, and that you can run higher order approximations with Dynare++. But I have also read an earlier post here saying that using the latest version of Dynare (as of May 2020 when the post was written), we can calculate higher order approximations. What is the easiest way to do this?

I will also note that I am using version 4.4.3, which I know is not the latest version. Perhaps this is part of the issue.

Any help is appreciated, thanks!

You should use Dynare 5.4 for this. Dynare++ is superseded.

Thanks, I’m happy to try that. With version 5.4, am I able to set the order in the same way as one does for orders 1-3?

i.e. something like: stoch_simul (drop=500, irf=20, order=4, nograph, noprint, k_order_solver, periods=1000); ?

Yes.
