Description: Empirical model building and process optimization using experimental design and statistical modeling. The first half of the course covers building empirical first- and second-order empirical models, (fractional) factorial designs, and process improvement with steepest ascent. The second half covers advanced topics including robust parameter design and mixture experiments. A final project requires small teams of students to identify a process of their choosing, improve that process, and document their work in a short final report.

Laptops running R: I encourage you to bring a laptop to class each day so you can try the R programming exercises in class. If you don’t have one, no problem, teamwork is encouraged — sit next to someone friendly who likes to share.
Student learning outcomes
At the end of the course, you will be able to:
1. Organize knowledge in graphs, tables, and code to support concise, comprehensible, and scientifically defensible written interpretations to produce knowledge.
2. Distinguish a testable scientific hypothesis or data-supported interpretation from an opinion.
3. Understand from a data story the goals of the study and apply the correct statistical procedure.
4. Explain the scientific aspects of a problem to nonscientists in a fashion that enhances understanding and decision making.
5. Understand fundamental concepts of matching experimental designs with analysis models.
6. Recognize types of experimental designs and analysis models.
7. Perform and interpret a proper response surface analysis.
8. Define parameters of interest and hypotheses in words and notation.
9. Summarize data visually, numerically, and descriptively and interpret the observed characteristics. Calculate and interpret numerical summaries such as the estimated stationary point and predicted response and confidence bounds for each, and create visual summaries such as contour and surface plots.
10. Use statistical software, such as R, to read and manage data, create informative plots, report numerical summaries, apply statistical models, by recommended programming practice including abstraction and documentation.
11. Design experiments to infer causal treatment effects.
12. Identify and explain the statistical methods, assumptions, and limitations used in reported studies in scientific literature or popular media.
13. Evaluate and criticize published studies, the work of peers, and your own work and assess what was done well, what could be done better, and examine whether their conclusions are supported using statistical principles.
14. Make evidence-based decisions by constructing and deciding between testable hypotheses using appropriate data and methods.
15. Discover relationships and make predictions through model development and selection.
Meeting the learning outcomes
You will acquire new information in this class, but the emphasis is comprehending, integrating, and applying information. Rote factual memorization is the lowest form of learning. Effective learning takes place by explaining, integrating, applying, and analyzing facts, hypotheses, and theories.
Learning in this class occurs by:
- Doing – completion of exercises that require analysis of data to answer questions and test hypotheses, or researching answers to reading assignments.
- Discussion – interaction with classmates to assemble and synthesize information you’d utilizing the collective skills and knowledge base of the group.
- Listening, acting, and reflecting – activities during class time provide insights into information not available in readings and includes review difficult material to aid comprehension. Note taking permits later reflection on lecture content. Listening to the professor lecture is the least effective learning tool for both students, however, and you should plan on coming to every class prepared to participate in active and reflective learning opportunities.
Learning without thought is labor lost.
What I hear, I forget.
What I see, I remember.
What I do, I understand.
Course grade is wholly homework and project-based. There are assignments associated with each chapter and one final project.
Semi-weekly homework: 75%
Final Project: 25% (Report, presentation, and contest.)
Rubrics guide assessment (and self-assessment) of homework, code, projects, exams, and presentations.
Homework is due 1 week (or 2 classes, whichever is shorter) after we complete each chapter. Extra points may be given for exceptional work based on the rubrics for homework and code. For example, if you earn a 5+5+5 on the rubric, then your grade will be increased by 10% of what you earned for doing exceptional work.
Header for homework assignments for each part:
RSM Stat 579.2
All R (or SAS) code for the assignment should be included with the part of the problem it addresses (for code and output use a fixed-width font, such as Courier). Do NOT use your R code and output as your answer to the problem, but include them to show me how you arrived at your answer. Your prose solution (in a non-fixed-width font) should be provided in addition to R output.
Please hand in a physical version of your homework and projects, I will write comments on it and give it back to you. An electronic version will be accepted under exception circumstances (almost never) — better to have a classmate print and bring it to class in your absence.
Late assignments will be penalized 20% if handed in by 5pm the following day, and will not be accepted after that. Please slide your late assignments under my office door (SMLC 312) after writing the date/time in the upper-left hand corner of when you’re turning it in.
Homework is designed to encourage you to review the material we’ve learned, synthesize new information from the R help pages or the web, and apply (and learn!) your new skills. Expect to spend 4-5 hours a week (outside of class!) to do well, and maybe double that to do outstandingly well.
My solutions posted after each HW is due will provide model answers to have a sense of the quality and content I’m looking for.
Collaboration and citation
For homeworks (and obviously team projects) I encourage you to work together. Please discuss the data, code, and problems with one another, but do your own exploration and write up. We expect everyone to hand in substantially different homeworks, and we will enforce this under the honor code. The small benefit you might get from plagiarism is not worth the severe penalty.
As in life, please use any resources available to you. Projects and some homeworks will explicitly encourage you to use resources on the internet, but showing extra initiative will always be appreciated. You may find R programming tough at first, so feel free discuss your problems with other classmates or meet with or email questions to me.
I encourage you to use the ideas of others, but make them your own, giving credit. For projects have a formal bibliography, for homework cite casually, and for code copy the URL in a comment (which is doubly helpful for finding the resource again).
Final project description – The final project requires small teams of students to improve the flight time of a paper helicopter. The project consists of planning, designing, conducting, and analyzing an experiment, using appropriate design-of-experiment principles, and then using an optimization strategy to improve the process to a stable optimum. Outcomes include a written project report with a final class presentation, as well as a competition between teams and the professor.
Working in teams is how science gets done. Each member of the team is responsible for every part of the project. I know team projects can be frustrating, requiring maturity, mutual consideration, and professionalism throughout, but I hope to teach some skills that should make it less painful.
Each project will receive a single grade, but individual grades will be weighted by effort as judged by the entire team if there are issues regarding unequal contribution.
Competition: 2011 Final project contest results and movie of drop, and class photo. John’s last words: “is that significant enough for you?”.
No exams. Note that the final project may take substantial time to develop and run experiments.
We will complete our final project presentations and contest before or on the scheduled final date and time.
