Struct Cube 

pub struct Cube;

Cubic density.

Suited for sub-Gaussian sources (e.g., uniform distributions).

The log-likelihood is: y⁴/4

Implementations

impl Cube

pub fn new() -> Self

Create a new Cube density.

Trait Implementations

impl Clone for Cube

fn clone(&self) -> Cube

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

Performs copy-assignment from source.

impl Debug for Cube

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

Formats the value using the given formatter.

impl Default for Cube

fn default() -> Cube

Returns the “default value” for a type.

impl Density for Cube

fn log_lik(&self, y: &Array1<f64>) -> Array1<f64>
