1 EST 504 (Remmenga) Chapter 11: Some Model Building and Diagnostic Tools in the REG procedure DATA SET 1. Use the Gifted data set (from Chapter 10) again. (I will call the SAS ® data set “GIFT” as before.) The GIFT data set can be found at the E ST 504 website ( http://web.NMSU.Edu/~martarem/EST_504.htm). Read it into SAS ® however you like. SAS PROGRAMMING and QUESTIONS (Please write your answers on the OUTPUT) 1. Print out the data and plot each X against Y. 2. Suggest a reasonable relationship between each X and Y based on the plots alone. 3. Use PROC CORR to obtain all pair-wise correlations among Y and the X’s. 4. Fit the full model in PROC REG and request the variance inflation factors (VIF’s). 5. Show how the VIF values relate to the results of the pair-wise correlations. 6. Based on the VIF values, obtain a set of variables that you believe to be free of multicolinearity and explain your choice of variables. 7. Using the set of variables from 6, apply three different automatic variable selection techniques provided by SAS ® .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
