Simplifying gamma function
Webb20 jan. 2009 · Many problems in mathematical analysis require a knowledge of the asymptotic behaviour of Γ(z + α)/Γ(z + β) for large values of z , where α and β are bounded quantities.Tricomi and Erdélyi in (1), gave the asymptotic expansion. where the are the generalised Bernoulli polynomials, see (2), defined by. In this note, we show that … WebbThe exact distribution of the linear combination α X + β Y is derived when X and Y are exponential and gamma random variables distributed independently of each other. A measure of entropy of the linear combination is investigated. We also provide computer programs for generating tabulations of the percentage points associated with the linear …

WebbThe beta function is defined as: B(p, q) = ∫[u^(p-1) * (1-u)^(q-1)]du from 0 to 1. Comparing this with our integral, we can see that p = 4 and q = 4: E(X) = 60 * B(4, 4) Now, the beta function is related to the gamma function by the following formula: B(p, q) = Γ(p) * Γ(q) / Γ(p+q) The gamma function is an extension of the factorial function. WebbDouble factorials are motivated by the fact that they occur frequently in enumerative combinatorics and other settings. For instance, n‼ for odd values of n counts Perfect matchings of the complete graph K n + 1 for odd n.In such a graph, any single vertex v has n possible choices of vertex that it can be matched to, and once this choice is made the …

There are analogous identities for functions related to the gamma function — log gamma, digamma, trigamma, etc. — that follow the same pattern. The diagram below helps to visualize the identity landscape. The conjugation identities all have the same form.
