Implementations§

Source§

impl<F: Float, C: PartialOrd + Clone> FittedLogisticRegression<F, C>

Source

pub fn set_threshold(self, threshold: F) -> FittedLogisticRegression<F, C>

Set the probability threshold for which the ‘positive’ class will be predicted. Defaults to 0.5.

Source

pub fn intercept(&self) -> F

Source

pub fn params(&self) -> &Array1<F>

Source

pub fn labels(&self) -> &BinaryClassLabels<F, C>

Get the model positive and negative classes mapped to their corresponding problem input labels.

Source

pub fn predict_probabilities<A: Data<Elem = F>>( &self, x: &ArrayBase<A, Ix2>, ) -> Array1<F>

Given a feature matrix, predict the probabilities that a sample should be classified as the larger of the two classes learned when the model was fitted.
