Fitting a polynomial function to data, accounting for uncertainty information associated with that data, is a problem that is commonly encountered in metrology and for which algorithms and software are widely available. For reasons of numerical stability, Chebyshev polynomials are often employed rather than monomials. The problem of fitting a polynomial function that is constrained to pass through the origin, again taking uncertainty information into account, which arises in a number of metrology areas, has not been addressed to the same extent. This paper describes algorithms to determine the best fit polynomial function passing through the origin to data, accounting for uncertainty, and using Chebyshev polynomials. Software that implements the algorithms, and is available free to download, is also described.
