Struct Mcd 

pub struct Mcd { /* private fields */ }

A configured FAST-MCD estimator.

Reproducible by default (a fixed-seed rand_chacha::ChaCha8Rng sub-stream per random start, so results are thread-count invariant even with the rayon feature on); configure with Mcd::seed / Mcd::fit_with_rng.

Implementations

impl Mcd

pub fn new() -> Self

A max-breakdown MCD with default search settings.

pub fn coverage(self, fraction: f64) -> Self

Retain a fraction ∈ (0.5, 1] of the observations instead of the max-breakdown default; the coverage is h = ⌊fraction · n⌋ (clamped to [p + 1, n]). Larger fraction trades breakdown for efficiency.

pub fn n_subsamples(self, n: usize) -> Self

Set the number of random elemental starts (default 500).

pub fn reweight(self, on: bool) -> Self

Enable or disable the one-step reweighting (default true).

pub fn seed(self, seed: u64) -> Self

Set the master RNG seed (default is a fixed internal constant).

pub fn control(self, control: Control) -> Self

Override the concentration-loop convergence control.

pub fn fit(&self, x: &Array2<f64>) -> Result<McdFit, RobustError>

Fit reproducibly from the configured seed.

pub fn fit_with_rng<G: Rng>( &self, x: &Array2<f64>, rng: &mut G, ) -> Result<McdFit, RobustError>

Fit drawing the master seed from a caller-supplied generator.
