Struct ParametricResidualization 

Source 
pub struct ParametricResidualization {
    pub coefficient_transform: Array2<f64>,
    pub row_space_correction: Array2<f64>,
}
Expand description

The span-preserving orthogonalization of a smooth design against a constraint block: the realized block becomes X·T − C·R.

See parametric_residualization_for_design for the derivation. T is the ordinary coefficient-space transform every basis already carries (it goes into the basis metadata and restricts the penalties); R is the part that is new, and it is what makes the construction cost no model dimension.

Fields§

§coefficient_transform: Array2<f64>

T — the coefficient-space transform, p × k.

§row_space_correction: Array2<f64>

R = B·T in the RAW constraint block’s own columns, q × k. The realized block is X·T − C·R, so a predict-time rebuild needs C at the new rows and this matrix, and nothing else.
