Lognormal: The Lognormal Distribution

Description

Hazard function and cumulative hazard function for the Lognormal distribution with parameters shape and scale.

Usage

hlnorm(x, meanlog = 0, sdlog = 1,
shape = 1 / sdlog, scale = exp(meanlog), log = FALSE)
Hlnorm(x, meanlog = 0, sdlog = 1,
shape = 1 / sdlog, scale = exp(meanlog), log.p = FALSE)

Arguments

x

vector of quantiles.

meanlog, sdlog

Mean and standard deviation in the distribution of the logarithm of a lognormal random variable.

shape, scale

shape and scale parameters, both defaulting to 1.

log, log.p

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

Value

• hlnorm gives the hazard function, and Hlnorm gives the cumulative hazard function.

  Invalid arguments will result in return value NaN, with a warning.

Details

This is a complement to the Lognormal distribution, see Lognormal for further details.
