hypergeometric_distribution: Hypergeometric Distribution Functions

Description

Functions to compute the probability density function, cumulative distribution function, and quantile function for the Hypergeometric distribution.

Usage

hypergeometric_pdf(x, r, n, N)
hypergeometric_lpdf(x, r, n, N)
hypergeometric_cdf(x, r, n, N)
hypergeometric_lcdf(x, r, n, N)
hypergeometric_quantile(p, r, n, N)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.

Arguments

x

quantile (non-negative integer)

r

number of successes in the population (r >= 0)

n

number of draws (n >= 0)

N

population size (N >= r)

p

probability (0 <= p <= 1)
