WebDec 7, 2024 · A probit regression is a version of the generalized linear model used to model dichotomous outcome variables. It uses the inverse standard normal distribution as a linear combination of the predictors. The binary outcome variable Y is assumed to have a Bernoulli distribution with parameter p (where the success probability is \ (p \in (0,1)\) ).
