Struct SmoothTestInput 

pub struct SmoothTestInput<'a> {
    pub beta: ArrayView1<'a, f64>,
    pub covariance: &'a Array2<f64>,
    pub influence_matrix: Option<&'a Array2<f64>>,
    pub coeff_range: Range<usize>,
    pub edf: f64,
    pub nullspace_dim: usize,
    pub residual_df: f64,
    pub scale: SmoothTestScale,
}

Inputs to wood_smooth_test. beta is the full coefficient vector; the term block being tested is beta[coeff_range]. covariance is the matching posterior covariance Σ̂ (full p×p; the diagonal block is sliced out). covariance must be the scale-included posterior covariance (mgcv Vb/Vp, i.e. H⁻¹ already multiplied by the dispersion φ̂), so the Wald statistic T = β̂'·Σ̂⁻·β̂ is dimensionless — the residual dispersion has already been divided out and the F-statistic is T/ref_df with no further φ̂ factor. influence_matrix is the optional coefficient-space influence F = H⁻¹ X'WX; when present tr(F_jj)² / tr(F_jj²) is used as the Wood-corrected reference d.f. edf is the smooth’s effective d.f. (rank truncation for the penalized subblock); nullspace_dim is the fixed-effect (unpenalized) leading dimension within the block. residual_df is the denominator d.f. for the Estimated-scale F branch.
