Description

When used in descriptions of variables, shocks, and parameters, or in equation labels, the double exclamation mark starts an alias (but the exlamation marks are not included in it). The alias can be used to specify, for example, a LaTeX code associated with the variable, shock, parameter, or equation. The aliases can be retrieved from the model code by using the appropriate query in the function model/get.

Example

!transition_variables
    'Output gap !! $\hat y_t$` Y_GAP

In the resulting model object, the description of the variables Y_GAP will be

Output gap

while its alias will be

$\hat y_t$.
