Task 1: Tutorial

• Practice R models presented in R Code for Textbook Examples in Chap 6.pdf.
• Read R tutorial on Regression. The data sets (women.R, mtcars.R and states.R) referenced in the tutorial are included

Problem 1: Concrete Slump Test Data

Once you completed tutorial task, perform the following to complete the problem.

• Create a scatterplot matrix of Concrete Slump Test Data and select an initial set of predictor variables
• Build a few potential regression models using Concrete Slump Test Data
• Perform regression diagnostics using both typical approach and enhanced approach
• Identify unusual observations and take corrective measures
• Select the best regression model
• Fine tune the selection of predictor variables
• Interpret the prediction results
