Implementations§

Source §

impl KernelDensity2D

Source

pub fn estimate( data_x: &[f64], data_y: &[f64], adjust: f64, n_points: usize, ) -> KdeResult<Self>

Compute 2D kernel density estimate using FFT-based convolution

§Arguments

data_x - X coordinates of data points

adjust - Bandwidth adjustment factor (default: 1.0)
n_points - Number of grid points per dimension (default: 128)

§Returns

KernelDensity2D with 2D density grid

Source

pub fn find_contour(&self, threshold: f64) -> Vec<(f64, f64)>

threshold - Density threshold (as fraction of max density)

§Returns

Vector of (x, y) coordinates forming the contour

Source

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

Get density value at a specific point (interpolated)
