Gamma

class stats_arrays.GammaUncertainty

Bases: stats_arrays.distributions.base.UncertaintyBase

The Gamma uncertainty distribution probability density function as a function of \(k\), the shape parameters, and \(\theta\), the scale parameter:

\[f(x;k,\theta) = \frac{x^{k-1}e^{-\frac{x}{\theta}}}{\theta^k\Gamma(k)}\]

The scale parameter \(k\) is shape, and \(\theta\) is scale. An optional location parameter, which offsets the distribution from the origin, can be specified in loc.
