WebbLogistic (logit) or probit regression models provide a conditional probability of an observation belonging to a particular category. Logit and probit models do not require assumptions as restrictive as discriminant analysis. Supporters of this approach argue that logit regression fits the characteristics of the default prediction problem. http://econometricstutorial.com/2015/03/logit-probit-binary-dependent-variable-model-stata/ Webb1 mars 2024 · Abstract. The probit regression model (PRORM) aims to model a binary response with one or more explanatory variables. The parameter of the PRORM is estimated using an estimation method called the maximum likelihood (ML), like a logistic model. When multicollinearity exists, ML performance suffers. china seafood scare

WebbAlbert and Chib pointed out that in the case of the probit regression model, use of these variance scalars can be viewed as a probability rule based on a family of t-distributions that represent a mixture of the underlying normal distribution used in the probit regression, since the normal distribution can be modeled as a mixture of t-distributions.
