This option provides the same behaviour as before the change in
60ef6bbdbd.
It is typically useful when doing several estimations in the same .mod file.
The purpose of this statement is to specify the options that apply to the whole
model, when there are several “model” blocks, so as to restore the symmetry
between those blocks (since otherwise one “model” block would typically bear
the options, while the other ones would typically have no option).
It still remains possible to specify the options on one “model” block, or even
spread accross several ones.
Closes: #19
Everything was already in place (since ages!), except that the parser interface
was missing.
Also fix the derivation formula for atanh, which was incorrect.
In particular, this implies that steady state values of endogenous in the
“occbin_constraints” block must now be specified using the STEADY_STATE()
operator (and not with a “_ss” suffix).
Moreover:
– make various simplifications to the fields generated under M_
– in the driver file, replace the call to occbin.initialize() by a few explicit operations
Ref. #68
Consequently drop “occbin” option to “model”.
Incidentally, allow more values in equation tag names (previously some keywords
such as “alpha” were disallowed).
Ref. #68
As the name implies, this option allows contemporaneous variables on the RHS.
The A0 matrix for contemporaneous variables is added as a second (optional)
output to the generated var_ar.m file. Note that for reduced-form VAR, this
matrix will be the identity.
Also, the user is now allowed to write the VAR models in a more flexible form:
the LHS must still be a single variable, but the RHS can be an arbitrary
expression (as long as it is linear, obviously). Internally, the preprocessor
now uses derivation to compute the coefficients of the AR and A0. This change
applies to both reduced-form and structural VAR models.
Ref. dynare#1785
For the time being, the preprocessor will refuse that this option be used with
any command other than estimation.
By the way, remove occbin_likelihood and occbin_smoother options to estimation.
Ref. dynare#569
This option was treated as a numeric value: it was a hack to ensure that the
name of the dseries object was printed without quotes in the driver file.
However, that would make the JSON output synctically incorrect.
This commits removes the hack, and treats the “series” option as a string
value (in the same way as for the “data” command). A modification of the MATLAB
code will thus be needed to accomodate the change.
Useful in identification and method_of_moments toolbox to set the tolerance which replaces very small numbers by hard zeros in unconditional second moments (particularly in pruned_state_space_system.m and disp_moments.m)
