Categorical Variables

Variables whose observations can take on only one of a finite set of values are called categorical variables. In the Extreme Optimization Numerical Libraries for .NET, categorical variables are implemented by the CategoricalVariable class.

Associated with each categorical variable is a scale that translates the object values into numerical values.
