Struct rand::distributions::LogNormal

pub struct LogNormal { /* fields omitted */ }

👎 Deprecated since 0.7.0:

moved to rand_distr crate

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.

Trait Implementations

impl Clone for LogNormal

fn clone(&self) -> LogNormal

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LogNormal

impl Distribution<f64> for LogNormal

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> f64

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T> where
    R: Rng,
    Self: Sized,
