The Independent Variables <- Previous: Direct Transformation
Independent or exogenous variables can be declared for all types
of estimations. And ARCH/GARCH models can include independent variables
in both the mean equations and the conditional variance equations.
Different estimations may include different sets of independent
variables and for this reason special keyword commands are required
to accomplish this. First, setIndVars is called with the complete
list of independent variables for a session. If all independent
variables in this list are to be included in all runs in the session,
the nothing more needs to be done. However, if the list of independent
variables differs by run, then additional calls are required to setIndEqs, for mean
equations, and setCVIndEqs for conditional variance equations.
