Orthogonal Polynomials (OPY) develops a more usable model than standard polynomials which have intercorrelated model term. OPY separates the effects of higher order model terms.

The orthogonal model has independent terms which accurately reflect the importance of each model term. It handles up to four (4) model terms. The output includes orthogonal coefficients, a regression analysis, statistical models, predicted versus actual residuals, ANOVA.
