A Method for Improving the Accuracy of Polynomial Regression Analysis

Summary: This paper presents a method for improving the accuracy of polynomial regression analysis. It is applicable when the relationship being investigated is between one independent and one dependent variable.The least squares equation which best "fits" the data is determined using the properties of orthogonal polynomials and the statistical technique known as Analysis of Variance. The major differences between this technique and the usual regression approach to curve fitting are also discussed.
