virtual int NextBinomial(

)

abstract NextBinomial : 
        n : int * 
        p : float -> int 
override NextBinomial : 
        n : int * 
        p : float -> int 

Parameters

n

Type: System.Int32
A int which specifies the number of Bernoulli trials.

p

Type: System.Double
A double which specifies the probability of success on each trial, .

Return Value

NextBinomial generates pseudorandom numbers from a Binomial distribution with parameters n and p. n and p must be positive, and p must be less than 1. The probability function (with n = n and p = p) is

for .

The algorithm used depends on the values of n and p. If or if p is less than a machine epsilon, the inverse CDF technique is used; otherwise, the BTPE algorithm of Kachitvichyanukul and Schmeiser (see Kachitvichyanukul 1982) is used. This is an acceptance/rejection method using a composition of four regions. (TPE equals Triangle, Parallelogram, Exponential, left and right.)
