Struct Huber 

pub struct Huber {
    pub c: f64,
    pub tol: f64,
    pub maxiter: usize,
}

Huber’s “proposal 2” joint location/scale estimator (Huber).

Estimates location μ and scale σ simultaneously for a 1-d sample by the fixed-point scheme of Venables & Ripley §5.5, using the one-step clipped-mean location update (norm = None in the reference).

Fields

c: f64

Clipping threshold c (default 1.5).

tol: f64

Convergence tolerance.

maxiter: usize

Maximum number of iterations.

Implementations

impl Huber

pub fn estimate(&self, a: &[f64]) -> Option<(f64, f64)>

Jointly estimate location and scale, returning (mu, scale).

Returns None if the iteration fails to converge within maxiter.

impl Default for Huber

fn default() -> Self
