HyperGeometric

case class HyperGeometric(p: Double = .5, n: Int = 5, pop: Int = 10, stream: Int = 0) extends Variate with Product with Serializable

This class generates HyperGeometric random variates. This discrete RV models the number of successes in n draws from a finite population.

p

the probability of success (red balls)

n

the number of draws (balls drawn)

pop

the size of the finite population (total number of balls)

stream

the random number stream
