Elementary probability
(see
below for more details) and at least one semester of
real analysis.

Homework
policy:
Homework
problems will be assigned periodically throughout the
semester. Each homework assignment will be graded:
late/missed homeworks will receive a grade of zero. Students
are welcome to discuss the homework problems with other
members of the class, but should prepare their final answers
on their own. If you have any questions concerning the
grading of homework, please speak first with the TA. If you
are absent from class when an assignment is returned, you
can get your homework from the TA during their office hours.
Exams:
There will be
one inclass midterm exam, and a comprehensive final
examination. Each will be closed book, closed notes.

Final 
50% 
Required Text: The
lectures will (roughly) follow Chapters 69 of the book "Statistical
Inference", Second Edition, by G. Casella and R.L. Berger,
Duxbury, 2002.
Prerequisites:
Students should be familiar with basic undergraduate
probability, including the topics listed below.
1. Basic properties of
probablities, random variables. Probability mass
functions and probability density functions. Cumulative
distribution functions.
2.
Binomial, geometric, hypergeometric, Poisson, and negative
binomial distributions.
3.
Gaussian, uniform, exponential, double exponential, gamma,
chisquared and beta distributions. F and t
distributions.
4. Joint probability mass/density functions, independence.
4.
Expected values, moments, variance and covariance.
5.
Distributions of functions of a random variable. General
change of variables formula.
Prerequisites
can
be found in Casella and Berger: 1.16, 2.13, 3.13, 4.13,
4.56, 5.12. (Note that these sections also contain
some material that is not prerequisite for the course.)
Students may also wish to consult the textbook "A
First Course in Probability", by Sheldon Ross, or the
``bootcamp'' lecture notes.
Tentative Syllabus: The course is intended to introduce students to
some of the basic ideas and techniques of (nonasymptotic)
statistical inference from a theoretical point of view. The
course is not measuretheoretic, but we will be
mathematically rigorous whenever possible. The following is
an overview of the topics covered.
1. Order statistics,
Stirling's formula and convexity.
2. Inequalities:
Jensen, Holder, CauchySchwartz, Association (correlation),
Markov and Chebyshev.
3.
Elements of decision theory. Admissability, Bayes and minimax
procedures.
4.
Principles of data reduction: Sufficiency, minimal
sufficiency, ancillarity and completeness (Chapter 6 of CB)
5.
Introduction to point estimation: maximum likelihood, method
of moments, information inequality, UMVUE (Chapter 7 of CB)
6.
Introduction to hypothesis testing: likelihood ratio tests,
NeymanPearson theory, extensions (Chapter 8 of CB)
7.
Introduction to confidence intervals: inverting test
statistics, pivotal quantities, optimality properties (Chapter
9 of CB)
