- Thursday, October 21: If you are looking for ideas for the project, there is a large collection of time series here.
- Tuesday, October 19: Information about the project has been posted here. A one-paragraph proposal is due on Wednesday, November 3. Please email it to bartlett at stat.
- Thursday, September 30: The first mid-term exam will cover all material up to and including today’s lecture. Here are some review questions from Shumway and Stoffer: 1.4, 1.5, 1.6, 1.9, 1.15, 1.16a, 2.6, 3.1, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.10, 3.11, 3.23a.
- Monday, September 27: Remember that the first mid-term exam will be in class (12:30-2:00) on Thursday, October 7. It will be an open-book exam: you can bring any material you like. Exam papers will be handed out at 12:40, the exam will go from 12:45 to 1:55. There will be 6 questions. You may answer all six if you wish; your grade will consist of the total from the best five questions. Each part will have a percentage written next to it – the percentage of the grade that it constitutes. Please take notice of this. The percentages reflect the relative significance of the relevant material, not how much time it will take to answer the question.
- Monday, August 30: Some R resources referred to in the first computer lab:
- Tuesday, August 24: To sign up for computer accounts, you will need to obtain a form from Joe. At the first lab section, on this Friday, August 27, Joe will have these forms available, and will also present an introduction to R.
You are encouraged to work in small groups on homework problems; it’s an excellent way to learn. However, you must write up the solutions on your own, and you must never read or copy the solutions of other students. Similarly, you may use books or online resources to help solve homework problems, but you must credit all such sources in your writeup and you must never copy material verbatim.
Any student found to be cheating risks automatically failing the class and being referred to the Office of Student Conduct. In particular, copying solutions, in whole or in part, from other students in the class or any other source without acknowledgment constitutes cheating.

The gradient field defines the steepest descent direction. The gradient flow dynamic defines a segmentation of the space into attraction bassins of the local minimizers. pic.twitter.com/wW0flPEWor
