The Frechet Distribution

Density, distribution function, quantile function and random generation for the Frechet distribution with location loc, scale scale, and shape shape.

dfrechet(x, loc = 0, scale = 1, shape = 1, log = FALSE)

pfrechet(q, loc = 0, scale = 1, shape = 1, lower.tail = TRUE, log.p = FALSE)

qfrechet(p, loc = 0, scale = 1, shape = 1, lower.tail = TRUE, log.p = FALSE)

rfrechet(n, loc = 0, scale = 1, shape = 1)

Arguments

x, q

Vector of quantiles.

loc

Vector of locations.

scale

Vector of scales.

shape

Vector of shapes.

log

Logical; If TRUE, values are returned on the log scale.

lower.tail

Logical; If TRUE (default), return P(X <= x). Else, return P(X > x) .

log.p

Logical; If TRUE, values are returned on the log scale.

p

Vector of probabilities.

n

Number of draws to sample from the distribution.
