Curve fitting by the orthogonal polynomials of least squares
The systems of orthogonal polynomials mainly used in practice are derived from a common general formula, which is established by the principle of least squares, utilizing results from the Finite Calculus. A simplified method of utilizing the Aitken-Chebyshev polynomials, by means of an extensive set of appended standard tables, is presented.
