Pareto Distribution

Description

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

Usage

dpareto(x, scale = 1, shape = 1, log = FALSE)

qpareto(p, scale = 1, shape = 1, lower.tail = TRUE, log.p = FALSE)

ppareto(q, scale = 1, shape = 1, lower.tail = TRUE, log.p = FALSE)

rpareto(n, scale = 1, shape = 1)

spareto(x)

Arguments

`x`	A numeric vector of values.
`scale`	scale parameter.
`shape`	A string of the column in data for the shape aesthetic.
`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.

Details

The pareto distribution has been deprecated as it is not suitable for SSD data. The functions are wrappers on the equivalent VGAM functions.

Value

A numeric vector.

Examples

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