Web19 mei 2024 · Proof: Mean of the gamma distribution. Theorem: Let X X be a random variable following a gamma distribution: X ∼ Gam(a,b). (1) (1) X ∼ G a m ( a, b). E(X) = a b. (2) (2) E ( X) = a b. Proof: The expected value is the probability-weighted average over all possible values: E(X) = ∫X x⋅f X(x)dx. (3) (3) E ( X) = ∫ X x ⋅ f X ( x) d x. Webcalculation of the expected value is the same as that for the average of a set of data, with relative frequencies replaced by probabilities. Warning: The expected value really ought to be called the expected mean.
