IncludeConstant

As of Version 7.0, IncludeConstant has been renamed to IncludeConstantBasis and is part of the built-in Wolfram Language kernel.

IncludeConstant

is an option for Regress and DesignMatrix that specifies whether a constant term is automatically included in the model.

Details and Options

  • To use IncludeConstant, you first need to load the Linear Regression Package using Needs["LinearRegression`"].
  • The default setting IncludeConstant->True adds a constant term to the set of basis functions if a constant is not already included.
  • The setting IncludeConstant->False leaves the set of basis functions unchanged.
  • In the output of DesignMatrix, the constant term is included as the first column.
