An approximation to the convolution of gamma distributions
Communications in Statistics - Simulation and Computation, 2016AbstractIn general, the exact distribution of a convolution of independent gamma random variables is quite complicated and does not admit a closed form.

Mixtures of Gamma Distributions With Applications
Journal of Computational and Graphical Statistics, 2001This article proposes a Bayesian density estimation method based upon mixtures of gamma distributions. It considers both the cases of known mixture size, using a Gibbs sampling scheme with a Metropolis step, and unknown mixture size, using a reversible jump technique that allows us to move from one mixture size to another.

Characterizations of the Normal and the Gamma distributions
Zeitschrift f�r Wahrscheinlichkeitstheorie und Verwandte Gebiete, 1973The Normal and the Gamma distribution, properly translated, are characterized by a uniformly minimum variance property of the sample mean. In fact, we answer in particular a question asked by Kagan in 1966. Also an optimality property of the sample variance is proved to characterize the Normal distribution.

The general form of the gamma distribution is $$ f(x\left| {\alpha ,\beta } \right.) = \beta ^\alpha x^{\alpha - 1} e^{ - \beta x} /\Gamma (x){\text{ }}\:x \geqslant 0 $$ The parameter α is a shape parameter and s a scale parameter.
