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
