Statistical modeling and inference are based on the mathematical theory of probability and solving practical problems usually requires integration or optimization in several dimensions. Thus this course requires a solid mathematical background (calculus and linear algebra at the level of MTH 103 and MTH 104) and proficiency in basic probability theory (MTH 135, STA 104, or STA 213); students without strong preparation in these will need to invest significant additional time to fill in the gaps. Solving all but the simplest problems also requires computer skills and familiarity with statistical software that will be taught in the weekly Discussion Section on Thursday afternoons.

The course text is Morris DeGroot, Probability and Statistics (2nd edn). All class materials are distributed on-line via the web; for example, you may view homework assignments (and sometimes class notes) on the Syllabus. A class e-mail directory will be available on-line.

The only way to be sure you're learning the course material is to
solve problems (or, as Sophocles put it, One must learn by doing
the thing; for though you think you know it, you have no certainty until
you try.) Only the simplest problems can be solved without the use
of a computer, so we will have weekly discussion section to introduce you
to statistical Computing using the
S-Plus
statistical computing environment. Ten weekly problem sets are assigned
through the on-line syllabus. Homeworks are
collected at the **START** of class each Wednesday, after which
solutions will be posted on the web. Late homeworks **will not** be
accepted for full credit without a Dean's
Excuse, but the lowest homework score will be dropped. Partial
credit is available for homeworks turned in no more than a few hours
late.

You may work with other students on the homework problems, but your final answers should be written up independently: copying homework solutions is not allowed. You are encouraged to ask the Professor and the TA for help on your homework, after you have tried to solve the problems on your own. Questions about homework scores should first be addressed to the TA.

**Help is available!** The TA and I both have office-hours (see
above); in addition, Duke Statistics maintains an open **Help Session** every
Mon-Thu afternoon (4-6pm) in room 211 Old Chem (just outside my office),
where a statistics graduate student will be happy to help you.

In-class Midterm Exams and Final Exam are closed-book and closed-notes with a formula sheet permitted (one-sided, 8½"×11" for each midterm, and two-sided, 8½"×11" for the final). You may (and probably should) bring to each exam a calculator capable of computing exponentials, powers, and factorials. Questions about exam scores should be taken up with the Professor. Last year STA114/MTH136 had only a single midterm (ps,pdf) test, covering material similar to that for this year's first test.

This exam and several other course materials are offered in PostScript form. The ACPub cluster computers are all configured properly to display and print PS documents; if your home computer is not, click here for Windows platforms and here for Linux or Macs to get the GSview add-in.

Course grades are based on two in-class Midterm Exams (20% each), ten weekly Homework assignments (25% total), and a cumulative Final Exam or Term Project (35%). Missed homeworks receive zero scores, but each student's two lowest homework scores are dropped. Late homeworks are penalized. Histograms and summary statistics of midterm and final exam grades will be added to the syllabus web page. Each student's current average and course grade are available from the instructor at any time.

Cheating on quizzes or exams, plagiarism on homeworks and projects, and other forms of academic dishonesty are violations of the Duke Honor Code and will be referred to the Undergraduate Judicial Board.

Students who miss tests or assignments due to illness (you must go
to Student Health or the Student Infirmary), family tragedy, religious
holiday observance, varsity athletic trip or class field trip, etc., or
who have three examinations scheduled within 24 hours, may be eligible
for a Dean's
Excuse to permit the work to be completed late without penalty (a
dean's excuse does *not* excuse a student from completing the work,
it only allows the work to be done late); check with your academic dean
for details. No excuse is needed simply for missing class, only for
missed assignments and examinations.
