ChoiceModel Class

This class implements a functionality of a discrete choice model, an approach widely used in land use and transportation modeling. In principal, a set of agents make choices from a finite set of possibilities (alternatives). The choice selection is based on probabilities derived from utilities. These are computed on the basis of given variables and coefficients. The model allows the coefficients to be also estimated within this framework. See also Section 14.1.5.

As there are many different aspects to consider in specifying a discrete choice model, the software has been designed in a modular way to accommodate substantial flexibility in configuring these models. Each component included in the model is passed as character string that determines the module$=$ class name (as a fully qualified name) in which the component is implemented.
