Review:

Presentation:

  • Building multiple regression models
    • Binary Variables (aka Dummy or Indicator variables)
    • Interaction Variables
    • Multicollinearity > Correlation analysis
  • Examples with textbook data: black_7e_excel_database

Activity:

  • Interpret Output from Presentation Examples (like Lesson 9)

Assignment:

  • Continue with the “Analyzing the Database” Problems 1-4 on p. 549 
  • For this assignment
    • Experiment with Binary variables using the “Consumer Food” worksheet
    • Experiment with Interaction Variables using the “Manufacturer” worksheet
    • Eliminate insignificant variables from the model
    • Attempt to maximize R-Squared and the F statistic simultaneously
    • Present output for the model you think is best for each problem (4 models).
