Struct ndarray_glm::logistic_link::Logit[−][src]

pub struct Logit {}

Expand description

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

Trait Implementations

[src]

impl Link<Logistic<Logit>> for Logit

[src]

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

[src]

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

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

[src]

pub fn nat_param<F>(
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.

[src]

pub fn adjust_errors_variance<F>(
 ArrayBase<OwnedRepr<F>, Dim<[usize ; 1]>>,
 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.

[src]

pub fn d_nat_param<F>(
&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
