7.3 - The Cumulative Distribution Function (CDF) STAT 414

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. WebApr 23, 2024 · A cumulative distribution function gives you a probability value for each real input, so the function itself is an element of the set $[0,1]^\mathbb{R}$. However, you can see here that in addition to being … gpx c303b clock radio
