__construct

__construct(array $x, array $y, ?array $w = null, ?float $lam = null)

gcv

gcv(float $lam, array $X, array $XtWX, array $wE, array $XtE, array $y): float

Generalised cross-validation objective at smoothing parameter lam (SciPy's _gcv).

query

query(array $xq): array

Evaluate the smoothing spline at the query point(s) (de Boor, via Tessero\Interpolate::BSpline).

tck

tck(): array

The clamped (t, c, k) triple, mirroring the BSpline returned by scipy.interpolate.make_smoothing_spline.
