Draw a random sample from a Binomial distribution

Usage

# S3 method for class 'Binomial'
random(x, n = 1L, drop = TRUE, ...)

Arguments

x: A Binomial object created by a call to Binomial().
n: The number of samples to draw. Defaults to 1L.
drop: logical. Should the result be simplified to a vector if possible?
...: Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

Value

Integers containing values between 0 and x$size. In case of a single distribution object or n = 1, either a numeric vector of length n (if drop = TRUE, default) or a matrix with n columns (if drop = FALSE).

Examples


set.seed(27)

X <- Binomial(10, 0.2)
X
#> [1] "Binomial(size = 10, p = 0.2)"

mean(X)
#> [1] 2
variance(X)
#> [1] 1.6
skewness(X)
#> [1] 0.4743416
kurtosis(X)
#> [1] 0.025

random(X, 10)
#>  [1] 5 0 3 1 1 2 0 0 1 1

pdf(X, 2L)
#> [1] 0.3019899
log_pdf(X, 2L)
#> [1] -1.197362

cdf(X, 4L)
#> [1] 0.9672065
quantile(X, 0.7)
#> [1] 3

cdf(X, quantile(X, 0.7))
#> [1] 0.8791261
quantile(X, cdf(X, 7))
#> [1] 7
