derivkit.local_polynomial_derivative.diagnostics module

Diagnostics for local polynomial derivative estimation.

derivkit.local_polynomial_derivative.diagnostics.make_diagnostics(x0: float, config: LocalPolyConfig, xs: ndarray, ys: ndarray, used: ndarray, coeffs: ndarray, degree: int, order: int, ok: bool) → Dict[str, Any]

Builds diagnostics dictionary.

Parameters:

• x0 – The center point for polynomial fitting.

• config – LocalPolyConfig instance with fitting settings.

• xs – An array of sample points (shape (n_samples,)).

• ys – An array of function evaluations (shape (n_samples, n_components)).

• used – A boolean array indicating which samples were used (shape (n_samples,)).

• coeffs – The polynomial coefficients (shape (degree + 1, n_components)).

• degree – The degree of the polynomial fit.

• order – The order of the derivative being estimated.

• ok – Whether the fit met the residual tolerances.

Returns:

A diagnostics dictionary.
