Class materials

Announcements (previous ones) or Follow @stats4eng

01 Feb: assignment 3 is posted; due on 08 February.
- 06 Feb: quite a few emails asking if enough information is provided, etc. General rule: if information isn't provided, and you think it should have been, use an assumed value, but clearly justify why you've assumed the value, and why you picked the value you did.
- 06 Feb: regarding question 2 and 3: the problem is sufficiently specified, it is just not obvious what you need to do. That's typical ... an industrial statistics problem doesn't present itself to you in the form: "Calculate a confidence interval ...."; you have figure you want to determine (the aim), and then what you need to calculate. It is an important skill to learn how to translate an industrial requirement into a statistical calculation.

05 Feb: solutions to assignment 2 are posted (PDF).
06 Feb: the weekly tests are going well so far, so the midterm for 4C3 is cancelled.
- Expect the grading part of the website to be ready during reading week.
- Expect a slightly longer than normal weekly test at the end of reading week, going into the next week. That test will cover all the course material.
