– Indicate whether we are trying to normalize the static or dynamic model
– If failed to normalize the static model, suggest to use the “no_static”
option
– Remove a superfluous error message
In a model with [static]/[dynamic] equations, if the user was using include_eqs
with a list of equations that does *not* contain equations marked
[static]/[dynamic], then the call to ModelTree::includeExcludeEquations(…,
static_equations=true) would have an empty list of equation tags (as stored
in tag_eqns).
The right behaviour in this case is to exclude all static equations. However,
the code would exclude none, and this would disrupt the equilibrium between
[static] and [dynamic] equations (since all [dynamic] equations were excluded
by the other call to the same method).
The fix consists in removing the shortcut that returns from the method if
tag_eqns is empty.
Consequently drop “occbin” option to “model”.
Incidentally, allow more values in equation tag names (previously some keywords
such as “alpha” were disallowed).

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.

Some evaluated blocks could be incorrectly merged, leading to wrong
results (e.g. blocks incorrectly marked as evaluable forward).
Bug introduced in 39407083be
This is inconsistent with the way they are printed in equations (without
underscores).
The practice of appending underscores only makes sense in a MATLAB workspace context.
Rather use a single vector as in non-block mode.
By the way, change the order of output arguments in static functions, to be
closer to the dynamic ones.
Temporary terms need to be computed per equation (as was done previously), and
not simply per block.
It’s necessary to track temporary terms per equation, because some equations
are evaluated instead of solved, and an equation E1 may depend on the value of
an endogenous Y computed by a previously evaluated equation E2; in this case,
if some temporary term TT of equation E2 contains Y, then TT needs to be
computed after E1, but before E2.
In particular, in dynamic models, temporary terms are now computed for
derivatives w.r.t. exogenous, and also w.r.t. endogenous variables that do not
belong to the block.
Also remove a message about elements below the cutoff that was no longer
correct (elements below the cutoff have no impact on the incidence matrix
outside of normalization).
By the way, remove the BlockType stuff which was purely informative (and it’s
not worth carrying over prologue and epilogue information just for that).
