RANDNBIN Generate Negative Binomial Random Variables

Section: Random Number Generation

Usage

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

Example

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

ans = 
 437 215 199 187 

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

ans = 
  471 1233  768  338
