WebGamma distributions are sometimes parameterized with two variables, with a probability density function of: f ( x, α, β) = β α x α − 1 e − β x Γ ( α) Note that this parameterization is equivalent to the above, with scale = 1 / beta. The probability density above is defined in the “standardized” form. To shift and/or scale the ...
