Implementations

impl Link

pub fn link(&self, mu: f64) -> f64

Apply link function: η = g(μ)

pub fn inverse_link(&self, eta: f64) -> f64

Apply inverse link: μ = g⁻¹(η)

pub fn derivative(&self, eta: f64) -> f64

Derivative of inverse link: dμ/dη

pub fn name(&self) -> &'static str

Get the name of the link function as a string

Trait Implementations

impl Clone for Link

fn clone(&self) -> Link

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Link

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Link

fn deserialize<__D>( __deserializer: __D, ) -> Result<Link, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Link

fn eq(&self, other: &Link) -> 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 Serialize for Link

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Link

impl StructuralPartialEq for Link
