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 = 
  <uint32>  - size: [1 4]
 
Columns 1 to 4
 150  274  304  159  
--> randnbin(6*ones(1,4),.01)
ans = 
  <uint32>  - size: [1 4]
 
Columns 1 to 4
 657  626  357  663
