Hazard function and
cumulative hazard function for the Lognormal distribution with
parameters shape and scale.
hlnorm(x, meanlog = 0, sdlog = 1,
shape = 1 / sdlog, scale = exp(meanlog), prop = 1, log = FALSE)
Hlnorm(x, meanlog = 0, sdlog = 1,
shape = 1 / sdlog, scale = exp(meanlog), prop = 1, log.p = FALSE)vector of quantiles.
Mean and standard deviation in the distribution of the logarithm of a lognormal random variable.
shape and scale parameters, both defaulting to 1.
A 'proportional hazards' parameter, see Details.
logical; if TRUE, probabilities p are given as log(p).
hlnorm gives the hazard function, and
Hlnorm gives the cumulative hazard function.
Invalid arguments will result in return value NaN, with a warning.
This is a complement to the Lognormal distribution, see
Lognormal for further details.
From eha version 2.3-0, the lognormal distribution is extended to a three-parameter family of distributions. The third parameter, 'prop', is a 'proportional hazards' parameter, simply multiplying the hazard function by its value. For now only implemented in the hazard and cumulative hazards functions, but it will be introduced fully soon. Probably as a class of distributions with a new name.
