Please send all regrade requests to the graders at email@example.com. Include:
Oct 7, 2013:
Both exams will be closed-book and closed-notes. We will provide a cheat sheet with the equations necessary. You will not need to recall R commands, but we may ask you to interpret the output of R functions without documentation.

If you have questions about homework or any of the lectures, please use our Piazza forum. You may join it using the link: www.piazza.com/stanford/fall2013/stats202.
Any other questions can he emailed to the staff mailing list:
Stats 202 meets MWF 1:15-2:05 pm at Skilling Auditorium (note the location change!).
All lectures will be recorded on video by the Stanford Center for Professional Development and posted here.
Stats 202 is an introduction to Data Mining. By the end of the quarter, students will:

The only textbook required is An Introduction to Statistical Learning with applications in R by Gareth James, Daniela Witten, Trevor Hastie, and Robert Tibshirani (Springer, 1st ed., 2013).
The book is available at the Stanford Bookstore and free online through the Stanford Libraries. A hard copy of the book is in the reserves of the Mathematics and Statistics Library.
If for extenuating circumstances you cannot take the midterm on October 28, you must email us by October 15. Since the midterm is during class, we cannot guarantee an opportunity to make it up.
The final exam is mandatory. If you cannot take it on the time indicated above, please drop the class.
There will be 7 graded homework assignments, due at the start of class on the day indicated. You may:
Late homework will not be accepted, but the lowest homework score will be ignored.
An important part of the class will be a quarter-long prediction challenge hosted by Kaggle. This competition will allow you to apply the concepts learned in class and develop the computational skills to analyze data in a collaborative setting.
Your goal will be to predict the employment status of middle-aged individuals during the 2008 financial crisis. We will use data from an ambitious longitudinal study made available by the National Bureau of Labor Statistics.

Invitations to the competition have been sent! If you haven't received one, please contact us. You may use our Piazza forum to form teams.
The 3 teams who obtain the highest score in the Kaggle competition will be given the option of not taking the final exam (!). Their class grade would be based on midterm and homework scores alone.
