Gamma expected value

WebExercise 1. Let be a Gamma random variable with parameters and . Let be another Gamma random variable, independent of , with parameters and . Find the expected value of the ratio. Solution. WebThe expected value and variance are two statistics that are frequently computed. To find the variance, first determine the expected value for a discrete uniform distribution using the following equation: The variance can then be computed as where , and f (x) is the probability mass function (pmf) of a discrete uniform distribution, or . Thus:
