Such choices contrast with standard consumption models in which the quantity of each good consumed is assumed to be a continuous variable. In the continuous case, calculus methods (e.g. first-order conditions) can be used to determine the optimum amount chosen, and demand can be modeled empirically using regression analysis. On the other hand, discrete choice analysis examines situations in which the potential outcomes are discrete, such that the optimum is not characterized by standard first-order conditions. Thus, instead of examining “how much” as in problems with continuous choice variables, discrete choice analysis examines “which one.” However, discrete choice analysis can also be used to examine the chosen quantity when only a few distinct quantities must be chosen from, such as the number of vehicles a household chooses to own [1] and the number of minutes of telecommunications s

Better to think in terms of the conditional distribution. I wouldn't go so far as to say 'no error term exists' as 'it's just not helpful to think in those terms'. So I wouldn't so much say it's a choice between 1. or 2. as I would say it's generally better to say "none of the above". However, irrespective of the degree to which one might argue for "1." or "2.", though, "3." is definitely wrong. Where did you see that? –Glen_b♦ Nov 20 '14 at 13:52 @Glen_b: Might one argue for (2)? I've known people to say it but never to defend it when it's questioned. –Scortchi♦ Nov 20 '14 at 14:49 2 @Glen_b All three statements have constructive interpretations in which they are true. (3) is addressed at en.wikipedia.org/wiki/Logistic_distribution#Applications and en.wikipedia.org/wiki/Discrete_choice#Binary_Choice. –whuber♦ Nov 20 '14 at 20:11 @whuber: I've corrected my answer wrt (3), which wasn't well thought through; but still puzzled about in what sense (2) might be right. –Scortchi♦ Nov 20 '14 at 21:27 1 @Scortchi Although you a
(academic discipline) Machine Learning Existence QuestionIs there an error term in logistic regression?If so, does it have a particular distribution, like the normal error in linear https://www.quora.com/Is-there-an-error-term-in-logistic-regression regression?UpdateCancelAnswer Wiki2 Answers Michael Hochster, PhD in Statistics, Stanford; Director of Research, PandoraWritten 75w ago · Upvoted by Peter Flom, Independent statistical consultant for researchers in behavioral, social and medical sciencesYou can think of the logistic regression model as arising from a linear model plus a logistic error term, but all you observe is a 1 if the logistic regression linear part plus error is positive and 0 if it is negative. This is called the latent variable formulation, and you can learn more details about it here:Logistic regressionYou can get other kinds of model (e.g. probit) by assuming a different distribution for the error term.3.9k Views · View UpvotesRelated QuestionsMore Answers BelowHow can the errors of logistic regression logit model example be modelled using likelihood principal?What does the bias term represent in logistic regression?Machine Learning: In layman's terms, what is the relationship between Grid Search and Logistic Regression?Are there researchers actively working on logistic regression?Why is logistic regression considered a linear model? Jay Verkuilen, PhD Psychometrics, MS Mathematical Statistics, UIUCWritten 75w ago · Upvoted by Justin Rising, MSE in CS, PhD in Statistics and Peter Flom, Independent statistical consultant for researchers in behavioral, social and medical sciencesYes but it's implicit. By assuming that the binary variable is Bernoulli conditionally on the regressors, we have chosen it as the error distribution. The regression is not linear though so it's not expressible as an additive error term.1.9k Views · View Upvotes · Answer requested by 1 personView More AnswersRelated QuestionsWhat is the difference between linear classification and logistic regression?What is logistic regression?What's the relationship between linear and logistic regression?What is autologistic regression in layman's terms and how is it related to logistic regression and Markov random field?Why is the asymptotic generalization error of logistic regression le
