Partial estimation of backward-looking semistuctural models

I am currently trying to figure out how to use Dynare for semistuctural models (both purely backward-looking or with VAR expectations).

I have discovered a reference to a routine which allows to estimate the model equation by equation (using OLS) here: tests/ecb/partial-estimation · master · Dynare / dynare · GitLab However, the code does not seem to work in the current version of Dynare + there is no documentation regarding this i te manual.

Are these routines available, and if yes, is there any kind of documentaton?

@stepan-a is the one who can answer this question.

I have managed to make a couple advancements wth regards to the code from GitLab - had to modify it in several places to match the updated internal functions underlying the simul_backward_model().

However, the estimation still does not work. Dynare throws an error:

Unrecognized function or variable ‘olseqs’.
Error in estimate (line 57)

The function olseqs seems to be missing. I tried to look for other instances of using it in the Git repository (here are the search results), but it is the only place where this routine is mentioned.

Am I missing something?
