- dev.nm.stat.random.rng.univariate.gamma.KunduGupta2007

All Implemented Interfaces:

RandomGammaGenerator, RandomNumberGenerator, Seedable
```
public class KunduGupta2007
extends Object
implements RandomGammaGenerator
```
Kundu-Gupta propose a very convenient way to generate gamma random variables using generalized exponential distribution, when the shape parameter lies between 0 and 1. This implementation is Algorithm 3 in the reference.
