Struct Uniform 

pub struct Uniform { /* private fields */ }

Implements the Uniform distribution.

Implementations

impl Uniform

pub fn new(lower: f64, upper: f64) -> Self

Create a new Uniform distribution with lower bound lower and upper bound upper.

Errors

Panics if lower > upper.

pub fn set_lower(&mut self, lower: f64) -> &mut Self

pub fn set_upper(&mut self, upper: f64) -> &mut Self

Trait Implementations

impl Clone for Uniform

fn clone(&self) -> Uniform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Continuous for Uniform

fn pdf(&self, x: f64) -> f64

Calculates the probability density function for the given Uniform distribution at x.

Remarks

Returns 0. if x is not in [lower, upper]

type PDFType = f64

fn ln_pdf(&self, x: Self::PDFType) -> f64

impl Debug for Uniform

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

Formats the value using the given formatter.

impl Default for Uniform

fn default() -> Self

Returns the “default value” for a type.

impl Distribution for Uniform

fn sample(&self) -> f64

Samples from the given Uniform distribution.

type Output = f64

impl Distribution1D for Uniform

fn update(&mut self, params: &[f64])

Update the parameters of the distribution.

fn sample_n(&self, n: usize) -> Vector

Generates a vector of n randomly sampled values from the given probability distribution.

fn sample_matrix(&self, nrows: usize, ncols: usize) -> Matrix

Generates a matrix of size n x m with values randomly sampled from the given distribution.

impl Mean for Uniform

fn mean(&self) -> f64

Calculates the mean, which for a Uniform(a, b) distribution is given by (a + b) / 2.

type MeanType = f64

impl Variance for Uniform

fn var(&self) -> f64

Calculates the variance of the given Uniform distribution.

type VarianceType = f64
