# shrinkage::Gaussian Shrinkage for Rust · 0.3.0 [Source]() ```rust pub struct Gaussian<'a> ``` A Gaussian response with an optional unpenalized fitted intercept. ## Inherent implementation [Source]() ```rust impl Gaussian<'_> ``` ### `fits_intercept` ```rust pub fn fits_intercept(&self) -> bool ``` [Source]() Whether fitting includes a free, unpenalized intercept. ### `response` ```rust pub fn response(&self) -> &[f64] ``` [Source]() Borrow the observed response. ## Inherent implementation [Source]() ```rust impl<'a> Gaussian<'a> ``` ### `fit_intercept` ```rust pub fn fit_intercept(self, enabled: bool) -> Self ``` [Source]() Enable or disable the unpenalized fitted intercept. Explicit column centering can still induce an original-scale intercept. ### `inverse_link` ```rust pub fn inverse_link(&self, eta: f64) -> Result ``` [Source]() Transform a predictor to a mean with the default link. #### Errors Reject nonfinite predictors or arithmetic. ### `link` ```rust pub fn link(&self, mu: f64) -> Result ``` [Source]() Transform a mean with the default identity link. #### Errors Reject means outside the link domain or nonfinite arithmetic. ### `new` ```rust pub fn new(response: &'a [f64]) -> Self ``` [Source]() Borrow a response, fitting an intercept by default. ### `with_link` ```rust pub fn with_link( self, link: L ) -> shrinkage::LinkedDatafit ``` [Source]() Compose this family with a link for Fisher-scoring IRLS. ## Implementation of Clone [Source]() ```rust impl<'a> Clone for Gaussian<'a> ``` ### `clone` ```rust fn clone(&self) -> Self ``` [Source]() ## [Implementation of ConvexLink](<45ae855dae253e1bbc77e093683e36c85f95b348ea7c924f536c479638434084>) [Source]() ```rust impl ConvexLink> for Identity ``` ## Implementation of Copy [Source]() ```rust impl<'a> Copy for Gaussian<'a> ``` ## [Implementation of CrossValidationDatafit](<98601fc9b50fbe6c319e8c6f7936102bb90fb9e942a9ce7e6cbd3d48de803c74>) [Source]() ```rust impl CrossValidationDatafit for shrinkage::Gaussian<'_> ``` ### `WithResponse` ```rust type WithResponse<'a> = Gaussian<'a>; ``` [Source]() ### `response` ```rust fn response(&self) -> &[f64] ``` [Source]() ### `supports_metric` ```rust fn supports_metric(&self, metric: ValidationMetric) -> bool ``` [Source]() ### `validate_training` ```rust fn validate_training(&self) -> Result<(), FitError> ``` [Source]() ### `validation_metric` ```rust fn validation_metric(&self) -> ValidationMetric ``` [Source]() ### `with_response` ```rust fn with_response<'a>(&self, response: &'a [f64]) -> Gaussian<'a> ``` [Source]() ## [Implementation of Datafit](<9d16367f3210bbbb9bf039290cf9c94f447e51d4ea33aea446a7f30e965d873a>) [Source]() ```rust impl Datafit for Gaussian<'_> ``` ### `Error` ```rust type Error = FitError; ``` [Source]() ### `value` ```rust fn value(&self, predictor: &[f64]) -> Result::Error> ``` [Source]() Evaluate `||response - predictor||² / (2n)`. ## Implementation of Debug [Source]() ```rust impl<'a> Debug for Gaussian<'a> ``` ### `fmt` ```rust fn fmt(&self, f: &mut core::fmt::Formatter<'_>) -> core::fmt::Result ``` [Source]() ## [Implementation of DiagonalHessianDatafit](<0c7a483f4e622180bfcc5efab524b3377e2104e91e0d263eb5a204d4a4ab722e>) [Source]() ```rust impl DiagonalHessianDatafit for Gaussian<'_> ``` ### `hessian_diagonal` ```rust fn hessian_diagonal( &self, predictor: &[f64], output: &mut [f64] ) -> Result<(), FitError> ``` [Source]() ## [Implementation of DifferentiableDatafit](<52561c3cc593c87f940a70abf79b463b0c969e6ea2f86d60ef4f213626b07d4b>) [Source]() ```rust impl DifferentiableDatafit for Gaussian<'_> ``` ### `fits_intercept` ```rust fn fits_intercept(&self) -> bool ``` [Source]() ### `gradient` ```rust fn gradient( &self, predictor: &[f64], output: &mut [f64] ) -> Result<(), FitError> ``` [Source]() ### `n_obs` ```rust fn n_obs(&self) -> usize ``` [Source]() ## Implementation of From [Source]() ```rust impl<'a> From> for Model<'a> ``` ### `from` ```rust fn from(value: Gaussian<'a>) -> Self ``` [Source]() ## [Implementation of GapSafeDatafit]() [Source]() ```rust impl GapSafeDatafit for Gaussian<'_> ``` ### `dual_candidate` ```rust fn dual_candidate( &self, predictor: &[f64], output: &mut [f64] ) -> Result<(), FitError> ``` [Source]() ### `dual_objective` ```rust fn dual_objective(&self, dual: &[f64]) -> Result ``` [Source]() ### `fenchel_gap` ```rust fn fenchel_gap(&self, predictor: &[f64], dual: &[f64]) -> Result ``` [Source]() ### `finalize_dual` ```rust fn finalize_dual(&self, dual: &mut [f64]) -> Result<(), FitError> ``` [Source]() ### `strong_concavity` ```rust fn strong_concavity(&self) -> f64 ``` [Source]() ## Implementation of HybridPathDatafit [Source]() ```rust impl HybridPathDatafit for shrinkage::Gaussian<'_> ``` ### `Outer` ```rust type Outer = (); ``` [Source]() ### `fit` ```rust fn fit( &self, design: &mut NativeDesign, penalty: &P, solver: &HybridCoordinateDescent, threshold: f64, work: (&mut Workspace
