Bernoulli

Bernoulli distribution

Description

Probability mass function, distribution function, quantile function and random generation for the Bernoulli distribution.

Usage

dbern(x, prob = 0.5, log = FALSE)

pbern(q, prob = 0.5, lower.tail = TRUE, log.p = FALSE)

qbern(p, prob = 0.5, lower.tail = TRUE, log.p = FALSE)

rbern(n, prob = 0.5)

Arguments

`x, q`	vector of quantiles.
`prob`	probability of success; (`0 < prob < 1`).
`log, log.p`	logical; if TRUE, probabilities p are given as log(p).
`lower.tail`	logical; if TRUE (default), probabilities are P[X ≤ x] otherwise, P[X > x].
`p`	vector of probabilities.
`n`	number of observations. If `length(n) > 1`, the length is taken to be the number required.

Examples

prop.table(table(rbern(1e5, 0.5)))
