Given N independent measurements x_i, let t=(x^_-mu)/(s/sqrt(N)), (1) where mu is the population mean, x^_ is the sample mean, and s is the estimator for population standard …
WebJan 24, 2024 · Correct cumulative distribution function notation. If I have a random variable, v A, distributed by CDF G on [ v 1, v 2], then is it correct to refer to the CDF as … 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.
