Probability density function for the Lomax distribution, with Mean parametrization.

Probability density function for the Lomax distribution, with Mean parametrization.

Usage

dlomax(x, mu, alpha, log = FALSE)

Arguments

x

Model space, defined for x >= 0

mu

Mean parameter of pdf, mu > 0

alpha

Alpha parameter of pdf, alpha > 1

log

Optional log argument, if true, return log(pdf)

Value

PDF of Lomax Distribution

Details

$$f(y | \mu, \alpha) = \frac{\alpha}{\mu(\alpha-1)} (1 + \frac{y}{\mu(\alpha-1)})^{-\alpha-1}$$

Examples

x <- seq(from = 0, to = 10, length.out = 100)
plot(x, dlomax(x, mu = 1, alpha = 2), type = "l")
