}

Fields

intercept_idx: usize

columns: Vec<LinearColumnConditioning>

Implementations

impl LinearFitConditioning

pub fn from_columns( design: &TermCollectionDesign, selected_cols: &[usize], ) -> Self

pub fn apply_to_design(&self, design: &Array2<f64>) -> Array2<f64>

pub fn transform_blockwise_penalties_to_internal( &self, penalties: &[BlockwisePenalty], p: usize, ) -> Vec<PenaltySpec>

Transform blockwise penalties through the conditioning.

For block-local penalties whose col_range does not overlap with any conditioning column, the transform is identity (the conditioning only affects unpenalized linear columns). In that common case the penalty passes through unchanged, avoiding O(p²) materialization entirely.

pub fn backtransform_beta(&self, beta_internal: &Array1<f64>) -> Array1<f64>

pub fn transform_penalized_hessian_to_original( &self, h_internal: &Array2<f64>, ) -> Array2<f64>

H_orig = M⁻ᵀ · H_int · M⁻¹, derived from L_int(β_int) = L_orig(M · β_int) via the chain rule.

pub fn internal_bounds_for( &self, col_idx: usize, min: f64, max: f64, ) -> (f64, f64)
