Webb4 sep. 2015 · Universality of Uniform (UoU) When you plug any CRV into its own CDF, you get a Uniform(0,1) random variable. When you plug a Uniform(0,1) r.v. into an inverse CDF, you get an r.v. with that CDF. For example, let’s say that a random variable Xhas CDF F(x) = 1 e x; for x>0 By UoU, if we plug Xinto this function then we get a uniformly WebbLog-Normal Distribution Derivation of Mean, Variance & Moments (in English) Computation Empire 2.11K subscribers Subscribe 13K views 2 years ago Probability Distributions Mean, Variance, MGF... 65歲打疫苗
