plotHyper {LearningStats}

Probability Mass and/or Distribution Function Representations associated with a Hypergeometric Distribution

Description

plotHyper represents the probability mass and/or the distribution function associated with a Hypergeometric distribution with parameters N, n and k.

Usage

plotHyper(N, n, k, type = "b", col = "grey")

Arguments

N

the population size.

n

the number of draws.

k

the number of success states in the population.

type

a character string giving the type of desired plot. The following values are possible: "b" (default) for probability mass function and distribution function representations together, "d" for distribution function representation and "p" for probability mass function representation.

col

a single colour associated with the probability mass function representation; default to "grey".

Value

A matrix containing the probability mass and the distribution function associated with each point of the support of a Hypergeometric distribution with parameters N, n and k.

Examples

N=20;n=12;k=5
plotHyper(N,n,k,type="d")
plotHyper(N,n,k,type="p",col="pink")
plotHyper(N,n,k)
