  If the full multiple regression needs modification, perform a stepwise regression and select the final model. Briefly note why you selected your final model. Interpret the coefficients of the final model only.

  That is, for the quadratic model the model adequacy is higher and the standard error of estimate is lower than that of the linear model. Hence we can conclude that the quadratic model is a better fit than the linear regression model.

  Socio-education and parents' education will be given moderate value for the regression model. All other factors will have lower values in the model.

  Thus 88.63% variability in the Heating Cost can be explained by the linear relationship between the Footage and Heating Cost (as described by the regression equation). The standard error of estimate of the regression model is 36.679.

• F test for Multiple Regression

  Above the output we give the regression model and the number of observations, n, used to perform the regression analysis under consideration. Using the appropriate model, sample size n, and output: 1.

• Heteroskedasticity

  It is true that we might have introduced some extra correlation and the R squre value might be a little inflated, but the ultimate regression model is still better than the model we had before because it at least satisfies all the regression assumptions
