Week 8: Discussion: Course Reflection

1. What is polynomial regression analysis?
2. What is the benefit of polynomial regression models?

Please share what you like about the class, and what if anything you would change (That is within reason — i.e., something that is possible given the goals for the course and the Ph.D. program).

• You may also share any feedback about the course textbook, videos, discussions, and assignments (separately or within the letter to your peers). 
• Also, are you on track with your learning goals for the term? What evidence do you have to support this?
