pub struct Logit {}

Expand description

The canonical link function for logistic regression is the logit function g(p) = log(p/(1-p)).

Trait Implementations

source

impl Link<Logistic<Logit>> for Logit

source

fn func<F: Float>(y: F) -> F

Maps the expectation value of the response variable to the linear predictor. In general this is determined by a composition of the inverse natural parameter transformation and the canonical link function. Read more

source

fn func_inv<F: Float>(lin_pred: F) -> F

Maps the linear predictor to the expectation value of the response.

source

impl<T> From<T> for T

const: unstable · source

fn from(t: T) -> T

Returns the argument unchanged.

source

impl<T, U> Into for T where
U: From<T>,

const: unstable · source

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T> Transform for T where
T: Canonical,

source

fn nat_param<F>(
lin_pred: ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>
) -> ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>> where
F: Float,

By defintion this function is the identity function for canonical links.

source

fn adjust_errors_variance<F>(
 errors: ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>,
 variance: ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>,
 _lin_pred: &ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>
) -> (ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>, ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>) where
 F: Float,

The canonical link function requires no transformation of the error and variance terms.

source

fn d_nat_param<F>(
lin_pred: &ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>
) -> ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>> where
F: Float,

The derivative of the transformation to the natural parameter. If it is zero in a region that the IRLS is in the algorithm may have difficulty converging. Read more

source

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
