WebA standard normal distribution has a mean of 0 and variance of 1. This is also known as a z distribution. You may see the notation N ( μ, σ 2) where N signifies that the distribution is normal, μ is the mean, and σ 2 is the … 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.
