Binomial Distribution

Description

Probability mass function (density) of the binomial distribution.

Usage

1
mu.dbinom(x, size, prob, log = FALSE)

Arguments

x

vector of quantiles. Missing values (NAs) are allowed.

size

vector of (positive integer) numbers of coin flips for which the Binomial distribution measures the number of heads.

prob

vector of probabilities of a head. If length(x) is larger than 1, then length(x) random values are returned.

log

logical; if TRUE, probabilities p are given as log(p).

mu.dbinom <- function(x, size, prob, log=FALSE)
  if (size==0) 1 else dbinom(x, size, prob, log=FALSE)

Value

Returns the density of bin(size, prob) at x.
