Lognormal distribution from its mean and coefficient of variation

The way severity assumptions are usually stated.

Usage

lognormal_from_mean_cv(mean, cv)

Arguments

mean

Mean of X; finite and positive.

cv

Coefficient of variation of X; finite and positive.

Value

A lognormal object.

Examples

d <- lognormal_from_mean_cv(1000, 0.5)
mean(d)
#> [1] 1000
sqrt(variance(d))
#> [1] 500
