Prominent Types of Discrete Choice Models
Discrete choice models can first be classified according to the number of available alternatives.
- * Binomial choice models (dichotomous): 2 available alternatives
- * Multinomial choice models (polytomous): 3 or more available alternatives
Multinomial choice models can further be classified according to the model specification:
- * Models, such as standard logit, that assume no correlation in unobserved factors over alternatives
- * Models that allow correlation in unobserved factors among alternatives
In addition, specific forms of the models are available for examining rankings of alternatives (i.e., first choice, second choice, third choice, etc.) and for ratings data.
Details for each model are provided in the following sections.

“The vain man does not wish so much to be prominent as to feel himself prominent; he therefore disdains none of the expedients for self-deception and self-outwitting. It is not the opinion of others that he sets his heart on, but his opinion of their opinion.”
—Friedrich Nietzsche (1844–1900)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
—Joshua Meyrowitz, U.S. educator, media critic. “The Blurring of Public and Private Behaviors,” No Sense of Place: The Impact of Electronic Media on Social Behavior, Oxford University Press (1985)
“Holofernes. He is too picked, too spruce, too affected, too odd as it were, too peregrinate as I may call it.
Sir Nathaniel. A most singular and choice epithet.”
—William Shakespeare (1564–1616)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
