Struct PaceFpcaConfig 

pub struct PaceFpcaConfig {
    pub ncomp: usize,
    pub bandwidth: f64,
    pub sigma2: f64,
    pub work_grid: Vec<f64>,
    pub alpha: f64,
}

Configuration for PACE sparse FPCA.

No #[non_exhaustive] — follows the crate::elastic_regression::ElasticPcrConfig convention for config structs (allows struct-literal construction in tests).

Fields

ncomp: usize

Number of FPCA components to extract.

bandwidth: f64

Kernel bandwidth for mean and covariance smoothing (must be strictly positive).

sigma2: f64

Caller-supplied measurement-error variance σ² (must be strictly positive).

σ² > 0 is required so that Σ_yi = Φ_i diag(λ) Φ_i^T + σ²I_{n_i} remains positive-definite regardless of the number of observed points per curve. Automatic σ² estimation from the raw-vs-smoothed diagonal is deferred.

work_grid: Vec<f64>

Work grid: the evaluation points at which mean, eigenfunctions, and fitted trajectories are represented. Must have at least 2 points and be sorted.

alpha: f64

Confidence level for bands (must be in the open interval (0, 1)). Default 0.05 → 95% pointwise bands.
