Programmatic prior mean for a coefficient penalty block.

This type now lives in the neutral gam-problem crate (with its inherent evaluate returning gam_problem::PriorMeanError); re-exported here so all existing crate::estimate::CoefficientPriorMean references keep resolving. Solver-side callers map PriorMeanError into EstimationError::InvalidInput. Programmatic prior mean for a coefficient penalty block.

The mean is evaluated once during penalty canonicalization and then enters the solver as the centering vector in (beta - mean)' S (beta - mean).

Variants

Zero

Scalar(f64)

Constant(ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>)

Functional

Fields

metadata: ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>

evaluator: Arc<dyn Fn(&ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>) -> ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>> + Send + Sync>

KernelBasis

Covariate-functional mean mu(a) = amplitude * K(a) for a coefficient block.

Formula-level coefficient groups pass their row/covariate metadata as covariates; the user-supplied kernel returns the block-sized basis vector K(a) and the scalar amplitude supplies alpha.

Fields

covariates: ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>

amplitude: f64

kernel: Arc<dyn Fn(&ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>>) -> ArrayBase<OwnedRepr<f64>, Dim<[usize; 1]>> + Send + Sync>
