CONSTANT and NOCONSTANT Subcommands (AREG command)

CONSTANT and NOCONSTANT indicate whether a constant term should be estimated in the regression equation. The specification overrides the corresponding setting on the TSET command.

• CONSTANT indicates that a constant should be estimated. It is the default unless changed by TSET NOCONSTANT prior to the current procedure.
• NOCONSTANT eliminates the constant term from the model.
