drgumbel(x, mu = 0, sigma = 1, log = FALSE)

prgumbel(q, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE)

qrgumbel(p, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE)

rrgumbel(n, mu = 0, sigma = 1)

Arguments

x, q

vector of quantiles.

mu, sigma

location and scale parameters.

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.

Details

The reversal-Gumbel distribution has density

f(x)=exp(-(x-μ)/σ-exp(-(x-μ)/σ)),

where -∞<μ<∞ is the location paramether and σ^2>0 is the scale parameter.
