IncludeConstantBasis

IncludeConstantBasis
is an option for LinearModelFit and other fitting functions which specifies whether a constant term should be included if not explicitly given in the list of basis functions.
  • The default setting IncludeConstantBasis->True adds a constant basis to the model if one is not specified in the list of basis functions.
  • Linear and generalized linear models typically compare the fitted model to the mean response model which contains only a constant basis function.
