Hypergeometric Distribution
The following functions are associated with the hypergeometric equation:
The parameters m, n, a, and b are integers satisfying max{0, n − b} ≤ m ≤ min{n, a}, and 0 for m elsewhere.
• dhypergeom(m, a, b, n)—Returns the probability density for the hypergeometric distribution.
• phypergeom(m, a, b, n)—Returns the cumulative probability distribution.
• qhypergeom(p, a, b, n)—Returns the inverse cumulative probability distribution for probability p.
• rhypergeom(m, a, b, n)—Returns a vector of m random numbers having the hypergeometric distribution.
Arguments
• m, n, a, b are integers, where 0 ≤ m ≤ a, 0 ≤ n − m ≤ b , 0 ≤ n ≤ a + b. To allow integration and other operations over these arguments, values outside of the stated range are allowed, but they produce a 0 result.
• p is a real probability, 0 ≤ p ≤ 1.
