    Hyatt Regency Montreal
    Montreal, Quebec, Canada

    Cosponsored by: American Statistical Association, ASA Section on Survey Research Methods, ASA Section on Government Statistics, International Association of Survey Statisticians, and Statistical Society of Canada

    We invite you to submit proposals for invited paper sessions for presentations to the third International Conference on Establishment Surveys (ICES-III) by December 1, 2005. The ICES-III Program Committee will review the proposals and notify session organizers by the end of February, 2006 if their proposal has been accepted or not. The deadline for contributed papers (including topic contributed sessions) will be June 15, 2006.

    The first International Conference on Establishment Surveys (ICES-I) in 1993 convened more than 400 experts in the area of surveys of businesses, farms and institutions. This conference set the stage by formally documenting the state of the art in 1993. In 2000 a second conference took a forward look at methods for surveying businesses, farms and institutions.

    The Conference will also include:

    • Three short courses on Monday, June 18
    • A keynote speaker and reception on Monday evening
    • Poster sessions, and software demonstrations throughout the conference
    • Following the conference, a CD ROM of all presented papers will be sent to all Conference participants

    Montreal is a city rich in history, art, culture, and learning and sports. It combines the smarts of North America with the laid back insouciance of Europe, high tech and high style. The city's architecture too is an artful mix of old and new, with graceful historic structures lovingly preserved and merged with the cool lines of the 21st century. The visual arts flourish here at the Montreal Museum of Fine Arts, the Musee D'art Contemporain, and hundreds of top-notch local galleries.

    All Conference activities will be held at the Hyatt Regency Montreal. The Hyatt Regency Montreal web site is http://montreal.hyatt.com/. (Hotel reservations will be open on March 1, 2007.)

    Attendees from outside Canada, and this could include United States passport holders, must ensure they have the proper travel documents e.g., passport, visa to enter and leave Canada.

    Prerequisite: Stat 201-2 or permission of instructor.

    Stat 265. Multivariate Analysis. Thursday, 06:10pm-08:40pm.
    Instructor: Dr. T. Nayak.

    Stat 273. Stochastic Processes. Monday, 6:10pm-8:40pm.
    Instructor: Dr. N. Singpurwalla.

    The course will start with an overview of probability theory needed for an appreciation of the underlying models and methods. It will then start with an introduction of the Bernoulli process (the mother of all processes) and in the sequel introduce will introduce notions as independent increments, the Markov property, the limit theorems, stopping rules and martingales. This in turn will be followed by Markov Chains, semi-Markov processes, renewal processes, Gaussian processes, Brownian motion, and the Brownian Bridge. Applications to problems in queueing, reliability, inventory, and finance will be mentioned, and if time permits toipics such as Markov additive processes and non-Gaussian processes such as the gamma and the beta will be covered.

    Stochastic processes have turned out to play a fundamental role in many disciplines, to include biology, economics, engineering, finance, operations research, and physics, to name a few. They form the building blocks of models and provide tools for the analyses of data in the context of statistical inference. Thus their appeal is universal.

    Prerequisities: The course will emphasize concepts over techniques. An introductory course in probability and some mathematical maturity (Stat 201-2) is all that is needed.

    Course Material: Lecture notes and topics from several books will be assembled.

    Stat 287. Modern Theory of Survey Sampling. Tuesday, 6:10pm-8:40pm.
    Instructor: Dr. P. Chandhok.

    The main objectives of the course are to provide a rigorous treatment of sampling theory and its applications.With this background the student can modify the existing theory, develop new theory, and better understand its applications. Graduate students from quantitative fields such as Statistics, Mathematics, Economics, Finance and Engineering as well as professionals working in government and private-sector companies, with an interest in survey sampling will benefit from this course. The prerequisites for the class are Statistics 91 (Principles of Statistical Methods) or equivalent and Math 32 (Single-Variable Calculus) or equivalent.

    This course will introduce the following topics: simple random sampling with and without replacement, systematic sampling, unequal probability sampling with and without replacement, ratio estimation, difference estimation and regression estimation.

    Stat 289. Statistical Method for Bioinformatics. Monday, 6:10pm-8:40pm.

    The objective of this course is to discuss statistical methods for bioinformatics. Microarrays have been widely used in biological and medical studies to identify disease related genes and to understand gene regulations. Microarray data analyses involve various statistical topics, such as multiples hypothesis testing and classification analyses. This seminar course will focus on the following topics: genomics and microarray basics, image processes, data transformation and normalization, differentially expressed gene identification, classification and cluster analysis, and other microarray related studies.

    Prerequisite: Stat 157 & 158 or equivalent, or permission of instructor.
