WebMar 7, 2024 · If we use symbol F for a cumulative distribution function, then F − 1 is its inverse (or quantile function). It is a standard notation for an inverse function of any function in mathematics. So Pr ( Z ≤ z) = F ( z) = p and z = F − 1 ( p) So it is not inverse of random variable Z, but inverse of its cumulative distribution function.
