LinearOffsetFunction

LinearOffsetFunction

is an option for linear and generalized linear model fitting functions that specifies a component for the model that is to be assumed known.

Details

  • LinearOffsetFunction is an option for LinearModelFit, GeneralizedLinearModelFit, LogitModelFit, and ProbitModelFit.
  • LinearOffsetFunction->func specifies that the model to be fitted should have a linear predictor of the form func[x1,x2,]+β0+β1 f1+β2 f2+.
  • LinearOffsetFunction defines a known component of the linear predictor for each data point.
