Rbinom n size prob

TīmeklisDensity, distribution function, quantile function and random generation for the binomial distribution with parameters size and prob. rbinom(n, size, prob) dbinom(x, size, prob, log = FALSE) pbinom(q, size, prob, lower.tail = TRUE, log.p = FALSE) TīmeklisThe binomial distribution with size = n and prob = p has density p (x) = choose (n, x) p^x (1-p)^ (n-x) for x = 0, …, n . Note that binomial coefficients can be computed by choose in R . If an element of x is not integer, the result of dbinom is zero, with a warning. p (x) is computed using Loader's algorithm, see the reference below.
