# Data Mining - Probit Regression (probability on binary problem)

## 1 - About

probit model (probability + unit) is a type of regression where the dependent variable can only take two values.

As the Probit function is really similar to the logit function, the probit model is really similar to a the logistic regression (ie binary logistic regression)

## 3 - Function

The probit function is the inverse of $\Phi(z)$, the cumulative distribution function of the standard normal distribution, and is denoted as $\Phi^{-1}(p)$.
