Gompertz Distribution

Description

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

Usage

dgompertz(x, llocation = 0, lshape = 0, log = FALSE)

pgompertz(q, llocation = 0, lshape = 0, lower.tail = TRUE, log.p = FALSE)

qgompertz(p, llocation = 0, lshape = 0, lower.tail = TRUE, log.p = FALSE)

rgompertz(n, llocation = 0, lshape = 0)

sgompertz(x)

Arguments

`x`	A numeric vector of values.
`llocation`	location parameter on the log scale.
`lshape`	shape parameter on the log scale.
`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, dgompertz(x), type = "l")
