Struct KdeSampler 

pub struct KdeSampler { /* private fields */ }

Axis-aligned Gaussian KDE over n samples in d dimensions.

Implementations

impl KdeSampler

pub fn fit(samples: &[Vec<f64>], bandwidth: Bandwidth) -> Result<Self>

Fit a KDE over samples (non-empty, rectangular, all finite).

pub fn n_samples(&self) -> usize

Number of fitted samples.

pub fn dims(&self) -> usize

Sample dimensionality.

pub fn bandwidths(&self) -> &[f64]

Fitted per-dimension bandwidths.

pub fn pdf(&self, point: &[f64]) -> Result<f64>

KDE density at point (Gaussian product kernel, length-checked).

pub fn draw(&self, u: f64, normals: &[f64]) -> Result<Vec<f64>>

Resample one synthetic particle: u in [0, 1) selects kernel centre floor(u * n); normals (one finite standard normal per dimension) perturbs it by width * z per dimension.
