STA 431 Assignment One: Quiz in Tutorial on Friday Sept. 18th

1. Read Section A.1 in Appendix A (Expected Value, Variance and Covariance). This is just review, and should be familiar. Do Exercises 1, 2 and 5-11; it should be fairly quick.
2. Read Section A.2 in Appendix A (Matrix Calculations). Much of this should be familar, but some of the material will be new to most students. Some of the new material will be covered in lecture as well.
   1. Do Exercises 1-10 (Multiple Choice!). If there are any multiple choice questions on the quiz, it will be a set of 5 or so, and you will need to get at least 4 out of 5 right to get any marks.
   2. Do Exercises 11, 12, 13, 14, 18
3. Read Section A.4.1 in Appendix A (Very basic math review). Do Exercises 1-3, or else just take a look and realize you know how to do them. If this part does not seem obvious, then I'm glad I included it.
4. Read Section A.4.2 in Appendix A (The first part of Maximum likelihood). Do Exercises 1 and 2, which are all paper and pencil. Next time we will do some numerical maximum likelihood with R, and then we will move on to SAS.
