public class NegativeBinomial
extends AbstractDiscreteDistribution

Negative Binomial distribution; See the math definition.

Instance methods operate on a user supplied uniform random number generator; they are unsynchronized.

Static methods operate on a default uniform random number generator; they are synchronized.

Implementation: High performance implementation. Compound method.

This is a port of nbp.c from the C-RAND / WIN-RAND library. C-RAND's implementation, in turn, is based upon

J.H. Ahrens, U. Dieter (1974): Computer methods for sampling from gamma, beta, Poisson and binomial distributions, Computing 12, 223--246.

Constructor Summary
`NegativeBinomial(int n, double p, RandomEngine randomGenerator)` Constructs a Negative Binomial distribution.

Method Summary
`double`	`cdf(int k)` Returns the cumulative distribution function.
`Object`	`clone()` Returns a deep copy of the receiver; the copy will produce identical sequences.
`int`	`nextInt()` Returns a random number from the distribution.
`int`	`nextInt(int n, double p)` Returns a random number from the distribution; bypasses the internal state.
`double`	`pdf(int k)` Returns the probability distribution function.
`void`	`setNandP(int n, double p)` Sets the parameters number of trials and the probability of success.
`static int`	`staticNextInt(int n, double p)` Returns a random number from the distribution with the given parameters n and p.
`String`	`toString()` Returns a String representation of the receiver.
