Description

The gamma distribution. This is a continuous probability distribution with two parameters, k and ϑ. If k is integral, the distribution represents the sum of k independent exponentially distributed random variables, each of which has a mean of ϑ.

-> GammaDistribution 

Create gamma distribution. This constructor do not check whether parameters are valid

Accessors
