public class NegativeBinomialextends AbstractIFunction
Negative binomial distribution. Returns the sum of the terms 0 through k of the Negative Binomial Distribution.k -- ( n+j-1 ) n j > ( ) p (1-p) -- ( j ) j=0
In a sequence of Bernoulli trials, this is the probability that k or fewer failures precede the n-th success.The terms are not computed individually; instead the incomplete beta integral is employed, according to the formula
y = negativeBinomial( k, n, p ) = Gamma.incompleteBeta( n, k+1, p ). All arguments must be positive, p[0] - scale factor
p[1] - the number of trials.
p[2] - the probability of success (must be in (0.0,1.0)).
