Statistics 101-106, (66101,66106), Introduction to Statistics (FALL)
Cross-listing: Statistics 501a-506a
Instructor: Mr. D. Pollard. T Th 1:00 pm - 2:15 pm
Each of these courses gives a basic introduction to statistics,
requiring no mathematics beyond high school algebra. Topics include
numerical and graphical summaries of data, probability, hypothesis
testing, confidence intervals, and regression. Each course focuses on
applications to a particular field of study and is taught jointly by
two instructors, one specializing in statistics and the other in the
relevant area of application. The Tuesday lecture, which introduces
general concepts and methods of statistics, is attended by all
students in Statistics 101-106 together. The course separates for
Thursday lectures, which develop the concepts with examples and
applications. Computers are used for data analysis. These courses are
alternatives; they do not form a sequence and only one may be taken
for credit. They do not count toward the natural sciences
requirement.

[Unofficial numbers: Statistics 211-213]
Cross-listing: Statistics 510b
Instructors: Mr. A. Barron, Mr. P. Belhemuer, Mr. J. Lees, Mr. J. Rust.
Each of these three courses introduce elements of probability and

the courses provide applications to particular fields of study.
Each course is taught jointly by two instructors, one
from the Statistics department and the other in the relevant fields of
study. The general lectures given by Andrew Barron are held on Mondays
and Wednesdays prior to the Spring Break (Jan 11 through Mar 3,
covering basic data analysis, probability and inference) and on
Mondays only after the break (Mar 22 through Apr 19, covering basics
of multivariate regression, random processes, and time series). These
general lectures are attended by all students in the three classes
together. The field specific lectures given by Professors Rust, Lees
and Belhumeur are held on Fridays only before the break (Jan 15
through Mar 5) and Wednesdays and Fridays after the break (Mar 24
through Apr 23). Field specific descriptions are given below.

Pattern recognition, or discrimination, is about guessing or
predicting the unknown nature of an observation, a discrete quantity
such as black or white, one or zero, sick or healthy, real or fake
according to Devroye, Gyorfi and Lugosi in "A probabilistic theory
of pattern recognition", Springer-Verlag (1996). Some of the
topics I intend to discuss are issues like consistency, error
probabilities and universality of many popular classification
rules. This course is aimed at computer scientists, engineers,
mathematicians, statisticians and anyone who is interested in the
theoretical aspects of pattern recognition. We will follow the
aforementioned book by Devroye, Gyorfi and Lugosi.
Time: Times to be arranged at organizational meeting.
