Struct SavedLinkWiggleRuntime 

pub struct SavedLinkWiggleRuntime {
    pub knots: Vec<f64>,
    pub degree: usize,
    pub penalty_metadata: Option<WigglePenaltyMetadata>,
    pub beta: Vec<f64>,
    pub index_shift: Option<Vec<f64>>,
}

Fields

knots: Vec<f64>

degree: usize

penalty_metadata: Option<WigglePenaltyMetadata>

Canonical penalty metadata is mandatory for standard fitted link-wiggles, whose posterior sampler consumes it. Other model classes do not expose the standard joint-wiggle sampling target.

beta: Vec<f64>

index_shift: Option<Vec<f64>>

Frozen-index mean-coordinate shift s (#2141). When present the predict layer evaluates the warp basis at the frozen index η̂ = base + X·s rather than at the de-aliased base predictor base, so predict reproduces the exact q (and deviance) the fit computed. This is mandatory for standard link-wiggle fits and None only for other model classes whose warp path never de-aliased, where the base predictor is already the warp index.

Implementations

impl SavedLinkWiggleRuntime

pub fn constrained_basis( &self, q0: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, basis_options: BasisOptions, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, FittedModelError>

pub fn design( &self, q0: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 2]>>, FittedModelError>

pub fn warp_index( &self, base: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, mean_design: &DesignMatrix, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, FittedModelError>

Reconstruct the exact index at which the saved link-wiggle basis is evaluated.

The frozen-basis de-aliased standard link fit persists a mean-coordinate shift s so its fitted warp index is base + X s (#2141). Other warp paths persist no shift and evaluate at base. Keeping this operation on the saved runtime gives prediction and public affine-design export one source of truth for the fitted coordinate frame.

pub fn basis_row_scalar( &self, q0: f64, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, FittedModelError>

pub fn apply( &self, q0: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, FittedModelError>

pub fn apply_with_index( &self, base: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, warp_index: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, FittedModelError>

Apply the warp with the additive base predictor base and the warp basis evaluated at a possibly distinct index warp_index (#2141): q = base + B(warp_index)·β. The frozen-basis de-aliased binomial-mean link fit pins B at the frozen index η̂, which differs from the de-aliased base predictor base by X·s; evaluating B at warp_index (= base + X·s) reproduces the exact q the fit scored. Monotonicity is certified at warp_index, where the link’s dq/dη = 1 + B'(warp_index)·β is defined. When no shift is active warp_index == base and this reduces to the original q = q0 + B(q0)·β.

pub fn derivative_q0( &self, q0: &ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, ) -> Result<ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>, FittedModelError>
