This is called the latent variable formulation, and you can learn more details about it here:Logistic regressionYou can get other kinds

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

Such choices contrast with standard consumption models in which the quantity of each good consumed is assumed to be a continuous variable. In https://en.wikipedia.org/wiki/Discrete_choice 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 service a customer decides to purchase.[2] Techniques such as logistic regression and probit regression can be used for empirical analysis of discrete choice. Discrete choice models theoretically or empirically model choices made by people among a finite set of alternatives. The models have been used to examine, e.g., the choice of which car to buy,[1][3] where to go to college,[4] wh
