Gamma

Base class: Distribution

Represents the Gamma distribution with shape parameter alpha (with default value 1.0) and scale parameter beta (with default value 1.0).

The probability density function is given by,

$$f(x |\alpha,\beta) = \frac{e^{-\frac{x}{\beta}}}{\beta^\alpha \[Gamma](index.md)(\alpha)}x^{\alpha - 1}.$$
