    pub value: f64,

Expand description

Block-local deterministic quadrature correction (issue #784).

value is Δ_b (added to the block marginal log-likelihood, subtracted from the REML/LAML cost); rho_gradient is the explicit penalty-score channel (a) of the gradient exactness contract; moments carries the channels (b)–(d) the gam-solve assembly contracts against fields it already owns.

Fields§

§value: f64

Δ_b: additive correction to the block marginal log-likelihood.

§rho_gradient: Array1<f64>

∂Δ_b/∂ρ, length rho_dim() — explicit channel (a) ONLY.

§quadrature_error: f64

Absolute difference between the five-node and three-node product rules, in the same log-likelihood units as value.

§node_count: usize

Number of nodes in the fine product rule.

§moments: Option<BlockQuadratureMoments>

Gradient-channel moments for the exact (b)–(d) assembly; None only when the block is empty (m == 0, where the correction is zero).
