WebbProbit regression, also called a probit model, is used to model dichotomous or binary outcome variables. In the probit model, the inverse standard normal distribution of the probability is modeled as a linear combination of the predictors.

"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. " - The probit regression model

WebbClassic fragility model: Probit regression. In past fragility studies, the vast majority of researchers have assumed that the fragility function is a two-parameter log-normal distribution function. In addition, parameter estimation for multiple stripes analysis data is typically performed using the maximum likelihood function approach. WebbOur outcome variable is binary, and we will use a probit model. Thus, our model will calculate a predicted probability of admission based on our predictors. The probit model does so using the cumulative distribution function of the standard normal. First, let us examine the dataset and our response variable.
