Hours: Mondays and Wednesdays 11am-12am
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 in-class midterm exam, and a comprehensive final examination. Each will be closed book, closed notes.
The default time is that listed in the course directory. The exam will be in class.
Grading: Course grades will be calculated as follows:
Required Text: The lectures will (roughly) follow Chapters 6-9 of the book "Statistical Inference", Second Edition, by G. Casella and R.L. Berger, Duxbury, 2002.
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
Binomial, geometric, hypergeometric, Poisson, and negative
3. Gaussian, uniform, exponential, double exponential, gamma, chi-squared and beta distributions. F and t distributions.
4. Joint probability mass/density functions, independence.
Expected values, moments, variance and covariance.
Distributions of functions of a random variable. General
change of variables formula.
be found in Casella and Berger: 1.1-6, 2.1-3, 3.1-3, 4.1-3,
4.5-6, 5.1-2. (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 (non-asymptotic) statistical inference from a theoretical point of view. The course is not measure-theoretic, 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.
Jensen, Holder, Cauchy-Schwartz, Association (correlation),
Markov and Chebyshev.
Elements of decision theory. Admissability, Bayes and minimax
4. Principles of data reduction: Sufficiency, minimal sufficiency, ancillarity and completeness (Chapter 6 of C-B)
5. Introduction to point estimation: maximum likelihood, method of moments, information inequality, UMVUE (Chapter 7 of C-B)
6. Introduction to hypothesis testing: likelihood ratio tests, Neyman-Pearson theory, extensions (Chapter 8 of C-B)
7. Introduction to confidence intervals: inverting test statistics, pivotal quantities, optimality properties (Chapter 9 of C-B)
Recommended Texts: These other texts offer good
coverage of some of the material in the course, at a more
advanced mathematical level.
