aesara.tensor.random.gamma = <aesara.tensor.random.basic.GammaRV object>[source]#

A gamma continuous random variable.

The probability density function for gamma in terms of the shape parameter $\alpha$ and rate parameter $\beta$ is:

$f(x; \alpha, \beta) = \frac{\beta^\alpha}{\Gamma(\alpha)}x^{\alpha-1}e^{-\beta x}$

for $x \geq 0$ , $\alpha > 0$ and $\beta > 0$ . $\Gamma$ is the gamma function:

$\Gamma(x) = \int_0^{\infty} t^{x-1} e^{-t} \mathrm{d}t$
