Probit analysis definition
Webb29 feb. 2024 · The probit (short for probability unit) link function is used to model the occurrence of an event that has a binary Yes/No outcome. This link function is expressed as the inverse of the Cumulative Distribution Function Φ (.) of the standard normal distribution N (0,1).
