gompertz: Gompertz Distribution

Description

Density, distribution function, quantile function, random generation and starting values for the Gompertz distribution.

Usage

dgompertz(x, lscale = 0, lshape = 0, log = FALSE)
qgompertz(p, lscale = 0, lshape = 0, lower.tail = TRUE, log.p = FALSE)
pgompertz(q, lscale = 0, lshape = 0, lower.tail = TRUE, log.p = FALSE)
rgompertz(n, lscale = 0, lshape = 0)
sgompertz(x)

Arguments

x

A numeric vector of values.

lscale

scale parameter on the log scale.

lshape

shape parameter on the log scale.

log

logical; if TRUE, probabilities p are given as log(p).

p

vector of probabilities.

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).

q

vector of quantiles.

n

number of observations.

Value

A numeric vector.

Details

The functions are wrappers on the equivalent VGAM functions that return a zero length numeric vector if x, q or p are zero length.
