Lognormal {eha}R Documentation

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).

Details

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

Value

hlnorm gives the hazard function, and Hlnorm gives the cumulative hazard function.
Invalid arguments will result in return value NaN, with a warning.
