Struct PaceFpcaResult 

#[non_exhaustive]
pub struct PaceFpcaResult {
    pub mean: Vec<f64>,
    pub eigenvalues: Vec<f64>,
    pub eigenfunctions: FdMatrix,
    pub scores: FdMatrix,
    pub fitted: FdMatrix,
    pub fitted_lower: FdMatrix,

}

Result of PACE sparse FPCA.

All matrix outputs are column-major FdMatrix (project-wide convention).

ncomp in the result may be less than the requested config.ncomp when the smoothed covariance surface yields fewer positive eigenvalues than requested (a finite-sample artifact of kernel estimation on sparse data).

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.

mean: Vec<f64>

Kernel-smoothed mean function on the work grid (length m).

eigenvalues: Vec<f64>

Functional eigenvalues (variance explained per component), length ncomp.

eigenfunctions: FdMatrix

Eigenfunctions on the work grid, shape m × ncomp (column-major).

scores: FdMatrix

BLUP (conditional-expectation) FPC scores, shape n × ncomp (column-major).

fitted: FdMatrix

Fitted trajectories on the work grid, shape n × m (column-major).

fitted_lower: FdMatrix

Lower pointwise confidence band, shape n × m.

fitted_upper: FdMatrix

Upper pointwise confidence band, shape n × m.

argvals: Vec<f64>

Work grid used for all outputs (clone of config.work_grid).

sigma2: f64

Measurement-error variance used (echoed from config).

ncomp: usize

Number of components actually extracted (may be < config.ncomp).
