Struct BlockSampledMarginal 

Source 
pub struct BlockSampledMarginal {
    pub value: f64,
    pub rho_gradient: Array1<f64>,
    pub importance_ess: f64,
    pub n_draws: usize,
    pub moments: Option<BlockSampledMoments>,
}
Expand description

Block-local sampled marginal 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.

§importance_ess: f64

Importance-sampling effective sample size (draws), for trust gating.

§n_draws: usize

Number of draws used.

§moments: Option<BlockSampledMoments>

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