Struct LqdFpcaResult 

#[non_exhaustive]
pub struct LqdFpcaResult {
    pub fpca: FpcaResult,
    pub fve: Vec<f64>,
}

Result of functional PCA on log-quantile-density (LQD) transformed densities.

All fields (fpca, scores, loadings, mean) are in LQD space on the uniform quantile grid t ∈ [0, 1], not in the original density space.

To obtain density-space variation modes, apply inverse_lqd to fpca.mean ± scale * loading_column for each principal component column.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fpca: FpcaResult

FPCA result in LQD space.

The FPCA is performed on the LQD-transformed densities on the uniform quantile grid t ∈ [0, 1]. Scores, loadings, and mean are all in LQD space, not density space.

fve: Vec<f64>

Fraction of variance explained by the first k components.

fve[k] = cumsum(sv²)[0..=k] / sum(all sv²). Monotone non-decreasing; fve.last() ≈ 1.0 only when ncomp == min(n_densities, n_quantile_pts).
