All Known Implementing Classes:

GammaDistribution, GammaDistributionFromMoments
```
public interface IGammaDistribution
extends IContinousPDF
```
Gamma distribution with shape parameter alpha > 0 (also called k in Wikipedia) and scale parameter theta > 0 (called lambda in umontreal.iro.lecuyer.probdist.GammaDist). The scale parameter theta is the inverse of the rate beta which is also sometimes given to characterise a Gamma distribution.
