Evaluating The Uncertainty Of Polynomial Regression Models Using Excel

. Regression analysis is widely used in experimental mechanical engineering to model physical properties and processes and to calibrate instruments. Standard textbooks address linear models and the uncertainties of linear models quite well. Usually, the texts adequately address multiple regression models based on several truly independent variables. The situation is more problematical with respect to multiple regression models that are polynomials in one variable such as the general quadratic model,
