On the Computation of Least Squares Polynomials Rounding error accumulated during digital computation of a least squares polynomial makes the computed polynomial only an approximation to the true least square polynomial. A simple method for adjust ing the constant term of the computed polynomial to get a better approximation to the true least squares polynomial is described. CACM January, 1967 Goldberg, M.
