The change implemented in 21a8a5794a broke the
testsuite and was incomplete.
– new option “overwrite” to provide the old behaviour (used to fix the testsuite);
– when concatenating several “estimated_params” block, the preprocessor now
checks that paramateres are not declared twice across blocks.
– Whenever possible, pass the “tex” option to Dynare commands instead of
fiddling with options_.TeX;
— For the remaining explicit options_.TeX and also for options_.debug,
use a boolean value instead of an integer.
With the former optimizer, the ML estimation under Octave would lead to a point
with a non-positive covariance matrix for shocks; in turn this would be an
unsuitable starting point for the subsequent Bayesian estimation
