WEPOR: A Weighted Polynomial Regression Program

Abstract

Two weighted least squares regression programs are documented and exemplified. Both programs apply to polynomial models with one independent variable. Program WEPOR was formulated for the case in which the error terms have different variances but are uncorrelated, whereas WEPOR2 deals with the problem of different variances and correlated error terms. Output from both programs include ANOVA (ANalysis Of VAriance) tables, predicted values of the dependent variable and the associated residuals, confidence and prediction limits for selected synthetic points, and a plot of the sample points, the regression curve, and the confidence and prediction limits.
