WebAccording to the documentation, you want to use the scale parameter (theta), but since you are defining beta, which is the inverse of theta, then you pass scale with the value of 1/beta, which in your example would be 1/3 or 0.33333. Therefore, try: y1 = stats.gamma.pdf (x, a=29, scale=0.33333) Share Improve this answer Follow 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 ,
