Gamma Distribution
Gamma distribution
Overview
This object defines a gamma distribution with "shape" parameter ( or ) and "scale" parameter ( or ). The probability density function, cumulative distribution function, and quantile are defined in Eq. (1), Eq. (2), and Eq. (3), respectively.
(1)(2)(3)where and . is the gamma function defined by Eq. (4), is the lower incomplete gamma function defined by Eq. (5), and is the inverse of the incomplete gamma function. and are computed using a custom iterative procedure, which obtains an accuracy of about .
