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).
