Struct rand::distributions::normal::LogNormal

pub struct LogNormal {
    // some fields omitted
}

Unstable (rand)

: use rand from crates.io

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.

Methods

impl LogNormal

fn new(mean: f64, std_dev: f64) -> LogNormal

Unstable (rand)

: use rand from crates.io

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

Panics

Panics if std_dev < 0.
