Answer true or false to each of the following statements and explain your answers. a. In a polynomial regression, the forward selection method and backward elimination method yield the same polynomial regression model. b. Because polynomial regression is able to model more complex curvature in the relationship between the response variable and predictor variable(s), extrapolation is an acceptable practice in polynomial regression. c. In a polynomial regression equation involving several predictor variables, we ordinarily consider models of order two.
