Homework

HW #1

• Due date: Feb. 12 (with a grace period that ends at noon on Thursday, Feb. 13)
• Here is a link to HW #1.
• Problems 1-3 are based on the Sec. 3.4 material covered during the 1st lecture. Problem 4 is based on some Sec. 5.3 material that will be covered during the 2nd lecture. (Since a lot of the first lecture of the semester pertains to material pertinent to Problems 1-3, and an example very similar to Problems 1 and 2 is discussed, it may be better to wait until after the first lecture to begin work on your solutions for this assignment.)
• 32 points

HW #2

• Due date: Feb. 26 (with a grace period that ends at noon on Thursday, Feb. 27)
• Here is a link to HW #2.
• These problems are based on Sec. 5.5 and Ch. 6 material that will be covered during the 3rd and 4th lectures. After lecture 3 you should be ready to do Problems 1, 2, and 4, but I think it may be best to not attempt the other parts of the assignment until after the 4th lecture (although I might cover the material most pertinent to Problem 3 (if I get through p. 86) so that it's a possiblity as well).
• Note: Some of the hints given near the top of the assignment are ones I give every time for HW 2. Some semesters, only some of the hints may be pertinent for the problems.
• I'll warn you that this assignment is longer and more difficult that HW #1. So I advise you to allow yourself plenty of time to work on it.
• Please recall that you are not supposed to discuss the extra credit portion of the assignment with anyone, or show anyone your work on it (and also that while you can discuss the other parts, you shouldn't share your solutions or answers to those with anyone either).
• 38 points, plus 2 extra credit points (total so far: 70 points, plus 2 extra credit points)

HW #3

• Due date: Mar. 25
• Here is a link to HW #3.
• Note that if you write your solutions by hand, you should make a clear distinction between upper-case X and lower-case x. (Estimators are functions of random variables and upper-case should be used. But lower-case should be used in estimates, likelihood functions, and in general for observed values of random variables.)
• Some of the parts of this assignment are rather straightforward and should be fairly simple, but there are other parts that you may find to be somewhat difficult.
• 54 points (total so far: 124 points, plus 2 extra credit points)

HW #4

• Due date: Apr. 8
• Here is a link to HW #4.
• Some of the techniques that can be used to solve Problems 1 and 2 are similar to those used in some of the UMVUE and CRLB examples in the class notes. (Also, some of the methods focused on in HW #1 may be useful as you work with Problem 1 of this assignment.)
• For Problem 3, I strongly suggest that you try to make use of the hints given with the problem.
• 42 points (total so far: 166 points, plus 2 extra credit points)

HW #5

• Due date: Apr. 22
• Here is a link to HW #5.
• 36 points (total so far: 202 points, plus 2 extra credit points)

HW #6

• Due date: May 6
• Here is a link to HW #6.
• Note: For Problem 5, you're expected to use tables or software to obtain any critical values needed to produce numerical values for the confidence bounds.
• Please recall that you are not suppose to discuss the extra credit portion of the assignment with anyone, or show anyone your work for it.
• 48 points, plus 8 extra credit points (total points for all assignments: 250 points, plus 10 extra credit points)
