Log Gamma Distribution

docs/tutorial:stats:continuous_loggamma

A single shape parameter $c > 0$ . The support is $x \in R$ .

where $γ$ is the lower incomplete gamma function, $γ (s, x) = \int_{0}^{x} t^{s - 1} e^{- t} d t$ .

μ_{n}^{'} = \int_{0}^{\infty} [lo g y]^{n} y^{c - 1} exp (- y) d y .

Implementation: scipy.stats.loggamma
