NominalVariables

NominalVariables
is an option for fitting functions such as LinearModelFit that specifies which variables should be treated as having discrete values specified by names.

DetailsDetails

  • Possible settings for NominalVariables include:
  • Automatictreat variables with non-numeric data values as nominal
    Alltreat all variables as nominal
    Nonetreat no variables as nominal
    {v1,v2,...}treat the variables as nominal
  • In linear models, a nominal variable v with possible values , , ... is represented as a collection of variables with values or corresponding to each case .
