I provided a mode file to the estimation command. But this file does not contain negative inverse hessian. So, naturally, I set the
cova_compute=1, expecting the dynare to compute it and run the mcmc afterwards. However, the estimation does not start, unless I give the negative inverse hessian.
My main question is: is this an intended feature or is it an issue in the codes?
Btw, I tried to look for the root of this behavior, and here is what I found so far:
driver.m (in line 269) calls the
which (in line 118) calls the
which (in line 109) calls the
which should compute and assign the value to
hh, i.e. hessian.
However, it doesn’t.
