RANDNBIN Generate Negative Binomial Random Variables

Section: Random Number Generation


Generates random variables with a negative binomial distribution. The general syntax for its use is
   y = randnbin(r,p)

where r is a vector of integers representing the number of successes, and p is the probability of success.

Function Internals

A negative binomial random variable describes the number of failures x that occur in x+r bernoulli trials, with a success on the x+r trial. The pdf is given by


Here we generate some negative binomial random variables:
--> randnbin(3*ones(1,4),.01)

ans = 
 150 274 304 159 

--> randnbin(6*ones(1,4),.01)

ans = 
 657 626 357 663
