Enum linfa_linear::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)
