The ADD statement adds independent
variables to the regression model.
Only variables used in the VAR statement or
used in MODEL statements before the first
RUN statement can be added to the model.
You can use the ADD statement interactively to add
variables to the model or to include a variable
that was previously deleted with a DELETE statement. Each use of the
ADD statement modifies the MODEL label.
See the "Interactive Analysis" section for an example.
