Project comments

• Manager and plant. Confounding.
• Low R-squared. Concentrate on practical implications.
• Partial-F. Common calculation error. Don't square the R-squared.
• Non-intuitive terms. Collinearity/missing variables.
• Split Plants. Talks about pro's and cons. Do they share any common cost structure?
• Point removal -- justify your actions.
• Write up. Executive summary most important. Annotated graphics for appendix.
• Grading -- within CLUSTER.
