# shrinkage::MultivariateFit Shrinkage for Rust · 0.3.0 [Source]() ```rust pub struct MultivariateFit ``` Original-scale feature-by-response coefficients and one intercept per response. Coefficients use [`CoefficientLayout`](<62149afd3598115cd84b1d082cb6c3684abff0b85239710acbface17a12565fe>)'s response-major storage. The objective and stopping diagnostics refer to the complete joint optimization-scale problem, including all responses. No dual certificate is reported. ## Inherent implementation [Source]() ```rust impl MultivariateFit ``` ### `coefficients` ```rust pub fn coefficients(&self) -> &[f64] ``` [Source]() Original-scale coefficients in response-major order. ### `coefficients_for_response` ```rust pub fn coefficients_for_response(&self, response: usize) -> Option<&[f64]> ``` [Source]() Original-scale feature coefficients for one response. ### `intercepts` ```rust pub fn intercepts(&self) -> &[f64] ``` [Source]() Original-scale intercepts, including each response's centering correction. ### `iterations` ```rust pub fn iterations(&self) -> usize ``` [Source]() Number of accepted joint proximal updates. ### `layout` ```rust pub fn layout(&self) -> CoefficientLayout ``` [Source]() Explicit feature and response dimensions of the fitted coefficients. ### `objective` ```rust pub fn objective(&self) -> f64 ``` [Source]() Final primal objective `P(beta_0, beta) = F(beta_0, beta) + R(beta)`. ### `predict` ```rust pub fn predict + ?Sized>( &self, x: &M ) -> Result, FitError> ``` [Source]() Predict response columns from raw training-order features. Entry `(observation, response)` has index `response * x.nrows() + observation`. Prediction uses fitted parameters without estimating new statistics. Empty prediction batches return an empty vector. #### Errors Reject feature-count mismatches, invalid entries, dimension overflow, or nonfinite arithmetic. ### `preprocessing` ```rust pub fn preprocessing(&self) -> &Preprocessing ``` [Source]() Shared training-feature normalization metadata. ### `step_size` ```rust pub fn step_size(&self) -> f64 ``` [Source]() Step that passed the final smooth quadratic-bound check. ### `stopping_criterion` ```rust pub fn stopping_criterion(&self) -> StoppingCriterion ``` [Source]() Criterion selected for the joint fit. ### `stopping_threshold` ```rust pub fn stopping_threshold(&self) -> f64 ``` [Source]() Absolute mapping threshold used to certify convergence. ### `stopping_value` ```rust pub fn stopping_value(&self) -> f64 ``` [Source]() Infinity norm of the complete coefficient mapping and all free-intercept derivatives, evaluated at the returned parameters. ### `termination` ```rust pub fn termination(&self) -> Termination ``` [Source]() Whether the joint fit converged or exhausted its iteration budget. ## Implementation of Clone [Source]() ```rust impl Clone for MultivariateFit ``` ### `clone` ```rust fn clone(&self) -> Self ``` [Source]() ## Implementation of Debug [Source]() ```rust impl Debug for MultivariateFit ``` ### `fmt` ```rust fn fmt(&self, f: &mut core::fmt::Formatter<'_>) -> core::fmt::Result ``` [Source]() ## Implementation of Freeze ```rust impl Freeze for MultivariateFit ``` ## Implementation of RefUnwindSafe ```rust impl RefUnwindSafe for MultivariateFit ``` ## Implementation of Send ```rust impl Send for MultivariateFit ``` ## Implementation of Sync ```rust impl Sync for MultivariateFit ``` ## Implementation of Unpin ```rust impl Unpin for MultivariateFit ``` ## Implementation of UnsafeUnpin ```rust impl UnsafeUnpin for MultivariateFit ``` ## Implementation of UnwindSafe ```rust impl UnwindSafe for MultivariateFit ``` ## Implementation of Any ```rust impl Any for T where T: 'static + ?Sized ``` ## Implementation of Borrow ```rust impl Borrow for T where T: ?Sized ``` ## Implementation of BorrowMut ```rust impl BorrowMut for T where T: ?Sized ``` ## Implementation of ByRef ```rust impl ByRef for T ``` ## Implementation of CastableFrom ```rust impl CastableFrom for DT where ST: ?Sized, DT: ?Sized ``` ## Implementation of CastableFrom ```rust impl CastableFrom for DT where ST: ?Sized, DT: ?Sized ``` ## Implementation of CloneToUninit ```rust impl CloneToUninit for T where T: Clone ``` ## Implementation of From ```rust impl From for T ``` ## Implementation of Imply ```rust impl Imply for U where T: ?Sized, U: ?Sized ``` ## Implementation of Into ```rust impl Into for T where U: From ``` ## Implementation of IntoEither ```rust impl IntoEither for T ``` ## Implementation of Pointable ```rust impl Pointable for T ``` ## Implementation of Read ```rust impl Read for T where T: ?Sized ``` ## Implementation of Same ```rust impl Same for T ``` ## Implementation of SupersetOf ```rust impl SupersetOf for SP where SS: SubsetOf ``` ## Implementation of ToOwned ```rust impl ToOwned for T where T: Clone ``` ## Implementation of TryFrom ```rust impl TryFrom for T where U: Into ``` ## Implementation of TryInto ```rust impl TryInto for T where U: TryFrom ```
