In probability theory and statistics, the probit function is the quantile function associated with the standard normal distribution, which is commonly denoted as N(0,1). Mathematically, it is the inverse of the cumulative distribution function of the standard normal distribution, which is denoted as Φ(z), so the probit is denoted as Φ⁻¹(p). It has applications in exploratory statistical graphics and specialized regression modeling of binary response variables.
