Log-Gumbel Distribution

Description

Probability density, cumulative distribution, inverse cumulative distribution, random sample and starting values functions.

Usage

dlgumbel(x, locationlog = 0, scalelog = 1, log = FALSE)

plgumbel(q, locationlog = 0, scalelog = 1, lower.tail = TRUE, log.p = FALSE)

qlgumbel(p, locationlog = 0, scalelog = 1, lower.tail = TRUE, log.p = FALSE)

rlgumbel(n, locationlog = 0, scalelog = 1)

slgumbel(x)

Arguments

`x`	A numeric vector of values.
`locationlog`	location on log scale parameter.
`scalelog`	scale on log scale parameter.
`log`	logical; if TRUE, probabilities p are given as log(p).
`q`	vector of quantiles.
`lower.tail`	logical; if TRUE (default), probabilities are `P[X <= x]`,otherwise, `P[X > x]`.
`log.p`	logical; if TRUE, probabilities p are given as log(p).
`p`	vector of probabilities.
`n`	number of observations.

Value

A numeric vector.

Examples

x <- seq(0.01, 5, by = 0.01)
plot(x, dlgumbel(x), type = "l")
