Lognormal3: The 3-Parameter Log Normal Distribution

In USGS-R/DVstats: Functions to manipulate daily-values data

The 3-Parameter Log Normal Distribution

Description

Density, distribution function, quantile function and random generation for the 3-parameter log normal distribution whose logarithm of the data minus lambda has mean equal to meanlog and standard deviation equal to sdlog.

Usage

dln3(x, meanlog = 0, sdlog = 1, lambda = 0)

pln3(q, meanlog = 0, sdlog = 1, lambda = 0)

qln3(p, meanlog = 0, sdlog = 1, lambda = 0, log = FALSE)

rln3(n, meanlog = 0, sdlog = 1, lambda = 0)

Arguments

x	vector of quantiles.
meanlog	the mean of the logarithm of the data minus lamda.
sdlog	the standard deviation of the logarithm of the data minus lamda.
lambda	the offset.
q	vector of quantiles.
p	vector of probabilities.
log	transform the quantiles by their natural logarithm?
n	number of observations.

Value

The density, cumulative probability, quantile,or random deviate.
