[−] Expand description

The log-normal distribution ln N(mean, std_dev**2).

If X is log-normal distributed, then ln(X) is N(mean, std_dev**2) distributed.

Implementations

impl LogNormal

pub fn new(mean: f64, std_dev: f64) -> LogNormal[−]

Construct a new LogNormal distribution with the given mean and standard deviation.

Panics

Panics if std_dev < 0.
