Random Variable From a Lognormal Distribution

Description

Generate random numbers from a lognormal distribution, rescaled to have user-specified population mean and standard deviation.

Usage

rlnorm_rs(n = 10, mui = 0, sigma = 1, rev = FALSE, pmean = 0, psd = 1)

Arguments

n	The number of random numbers to generate.
mui	The parameter mui to be used by stats::rlnorm().
sigma	The parameter sigma to be used by stats::rlnorm().
rev	If TRUE, the distribution is revered to generate a negatively skewed distribution. Default is FALSE.
pmean	Population mean.
psd	Population standard deviation.

Details

First, specify the parameter, mui and sigma, and the desired population mean and standard deviation. The random numbers, drawn from a lognormal distribution by stats::rlnorm(), will then be rescaled with the desired population mean and standard.

Value

A vector of the generated random numbers.

Examples

set.seed(90870962)
x <- rlnorm_rs(n = 5000,
               mui = 0,
               sigma = 1,
               pmean = 0,
               psd = 1)
mean(x)
sd(x)
hist(x)
