Struct Ogk 

pub struct Ogk<S = Qn> { /* private fields */ }

A configured OGK estimator, generic over the robust univariate scale (the default Qn is Maronna & Zamar’s recommendation; the location functional paired with it is the median).

Implementations

impl<S: ScaleEstimator> Ogk<S>

pub fn new(scale: S) -> Self

Create an OGK estimator with the given robust scale, two orthogonalization iterations and reweighting on.

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

Set the number of orthogonalization iterations (default 2).

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

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

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

Fit the estimator to the n × p data matrix x.
