Struct GaussianKde 

pub struct GaussianKde { /* private fields */ }

A fitted Gaussian kernel density estimator over a one-dimensional sample.

Holds the observations and the squared bandwidth (kernel variance) derived from them, so density queries reuse a single bandwidth computed once at fit time. Fields are private to keep the sample and its derived bandwidth an invariant pair; query the estimate with GaussianKde::density / GaussianKde::density_at.

Implementations

impl GaussianKde

pub const fn variance(&self) -> f64

The kernel variance h² (squared bandwidth) shared by every kernel.

pub fn bandwidth(&self) -> f64

The kernel bandwidth h (standard deviation of each Gaussian bump).

pub fn density_at(&self, x: f64) -> f64

Evaluates the estimated density at a single query point x.

Arguments

• x — the point at which to evaluate the density.

Returns

The estimated density f(x) ≥ 0.

pub fn density(&self, xs: &[f64]) -> Vec<f64>

Evaluates the estimated density at every query point in xs.

Arguments

• xs — the points at which to evaluate the density.

Returns

One estimated density per query point, in the input order.

Trait Implementations

impl Clone for GaussianKde

fn clone(&self) -> GaussianKde

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GaussianKde

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

Formats the value using the given formatter.

impl PartialEq for GaussianKde

fn eq(&self, other: &GaussianKde) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
