fit_residual¶
- sofia_redux.toolkit.resampling.fit_residual(data, phi, coefficients)[source]¶
Calculates the residual of a polynomial fit to data.
The residual is calculated using the matrix operation Y - CX where Y is the
dataset
, C are thecoefficients
and X is thephi
polynomial terms.- Parameters:
- datanumpy.ndarray (n_samples,)
Data from which coefficients were derived.
- phinumpy.ndarray (n_terms, n_samples)
Polynomial terms of independent values of each sample.
- coefficientsnumpy.ndarray (n_terms,)
Coefficient values.
- Returns:
- residualnumpy.ndarray (n_samples,)
The residual
