Enum SmoothKind 

pub enum SmoothKind {
    S,
    Te,
    T2,
    Ti,
}

Variants

S

Te

T2

Tensor smooth (t2(...)) using mgcv’s separable penalty decomposition: the tensor coefficient space is split into marginal penalized/null-space tensor subspaces, with one smoothing parameter per non-null subspace.

Ti

Tensor interaction smooth (ti(...)): a tensor-product smooth whose marginal main effects are excluded, so the term captures only the pure interaction between its variables. Materializes through the same tensor path as SmoothKind::Te but with per-margin sum-to-zero identifiability (TensorBSplineIdentifiability::MarginalSumToZero).
