Implementations

impl MEstimatorType

pub fn weight(&self, residual: f64) -> f64

Compute the weight function ψ(r)/r for a given residual

pub fn efficiency(&self) -> f64

Get the asymptotic efficiency of the estimator

pub fn breakdown_point(&self) -> f64

Get the breakdown point of the estimator

Trait Implementations

impl Clone for MEstimatorType

fn clone(&self) -> MEstimatorType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MEstimatorType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MEstimatorType

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for MEstimatorType

fn eq(&self, other: &MEstimatorType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for MEstimatorType

impl StructuralPartialEq for MEstimatorType
