Enum Link

pub enum Link {
    Identity,
    Log,
    Logit,
}

Link functions used by GLM

Variants

Identity

The identity link function g(x)=x

Log

The log link function g(x)=log(x)

Logit

The logit link function g(x)=logit(x)

Implementations

impl Link

pub fn link<A: Float>(&self, ypred: &Array1<A>) -> Array1<A>

Compute the link function g(ypred)

The link function links the mean ypred=E[y] to the so called linear predictor, g(ypred)=linear predictor

pub fn link_derivative<A: Float>(&self, ypred: &Array1<A>) -> Array1<A>

Computes the derivative of the link g'(ypred)

pub fn inverse<A: Float>(&self, lin_pred: &Array1<A>) -> Array1<A>

Computes the inverse link function h(linear predictor)

Gives the inverse relationship between the linear predictor and the mean ypred=E[y], i.e. h(linear predictor)=ypred

pub fn inverse_derviative<A: Float>(&self, lin_pred: &Array1<A>) -> Array1<A>

Computes the derivative of the inverse link function h'(linear predictor)

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

Formats the value using the given formatter.

impl Hash for Link

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
