Trait Implementations

impl Debug for LinearError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LinearError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for LinearError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<A: Float, D: Data<Elem = A>, T: AsTargets<Elem = A>> Fit<ArrayBase<D, Dim<[usize; 2]>>, T, LinearError> for TweedieRegressor

type Object = FittedTweedieRegressor<A>

fn fit(&self, ds: &DatasetBase<ArrayBase<D, Ix2>, T>) -> Result<Self::Object>

impl<F: Float, D: Data<Elem = F>, T: AsTargets<Elem = F>> Fit<ArrayBase<D, Dim<[usize; 2]>>, T, LinearError> for LinearRegression

type Object = FittedLinearRegression<F>

fn fit(
    &self,
    dataset: &DatasetBase<ArrayBase<D, Ix2>, T>
) -> Result<Self::Object>

Fit a linear regression model given a feature matrix X and a target variable y.

The feature matrix X must have shape (n_samples, n_features)

The target variable y must have shape (n_samples)

Returns a FittedLinearRegression object which contains the fitted parameters and can be used to predict values of the target variable for new feature values.
