What is the difference between the Beta and Gamma distribution?

WebBy definition, the Beta function is B ( α, β) = ∫ 0 1 x α − 1 ( 1 − x) β − 1 d x where α, β have real parts > 0 (but in this case we're talking about real α, β > 0 ). This is related to the Gamma function by B ( α, β) = Γ ( α) Γ ( β) Γ ( α + β) Now if X has the Beta distribution with parameters α, β , WebFeb 22, 2024 · Beta and gamma functions are popular functions in mathematics.
