Bernoulli function

Bernoulli distribution

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

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 $P[X \le x]$

  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)))
