Struct rand::distributions::FisherF

pub struct FisherF { /* fields omitted */ }

Deprecated since 0.7.0:

moved to rand_distr crate

The Fisher F distribution F(m, n).

This distribution is equivalent to the ratio of two normalised chi-squared distributions, that is, F(m,n) = (χ²(m)/m) / (χ²(n)/n).

Methods

impl FisherF

pub fn new(m: f64, n: f64) -> FisherF

Create a new FisherF distribution, with the given parameter. Panics if either m or n are not positive.

Trait Implementations

impl Distribution<f64> for FisherF

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

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

Important traits for DistIter<D, R, T>

impl<D, R, T> Iterator for DistIter<D, R, T> where
    D: Distribution<T>,
    R: Rng,  type Item = T;

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

Create an iterator that generates random values of T, using rng as the source of randomness.

impl Copy for FisherF

impl Clone for FisherF

fn clone(&self) -> FisherF

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FisherF

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
