Consider the jet engine thrust data in Exercises 12-108
Chapter 12, Problem 113SE(choose chapter or problem)
Consider the jet engine thrust data in Exercises 12-108 and 12-109. Define the response and regressors as in Exercise 12-109.
(a) Use all possible regressions to select the best regression equation, where the model with the minimum value of \(M S_{E}\) is to be selected as “best.’’
(b) Repeat part (a) using the \(C_{p}\) criterion to identify the best equation.
(c) Use stepwise regression to select a subset regression model.
(d) Compare the models obtained in parts (a), (b), and (c).
(e) Consider the three-variable regression model. Calculate the variance inflation factors for this model. Would you conclude that multicollinearity is a problem in this model?
