Description

This is a course about random variables, especially about their convergence and conditional expectations, motivating an introduction to the foundations of modern Bayesian statistical inference. It is a course by and for statisticians, and does not give thorough coverage to abstract measure and integration (for this you should consider MTH241) nor to the abstract mathematics of probability theory (see MTH 287).

Mathematical topics from real analysis, including parts of measure theory, Fourier and functional analysis, are introduced as needed to support a deep understanding of probability and its applications. Topics of later interest in statistics (e.g., regular conditional density functions) are given special attention, while those of lesser statistical interest (e.g., extreme value theorems) may be omitted.

Some problems and projects may require computation; you are free to use whatever environmnent you're most comfortable with. Most people find the R or S-Plus dialects of S (some notes are available) or Matlab (a primer is available) easier to use than compiled languages like Fortran or C. Homework problems are of the form chapter/problem from the text. Not all of them will be graded, but they should be turned in for comment; Monday classes will begin with a class solution of one or two of the preceeding week's problems. Some weeks will have lecture notes added (click on the "Week" column if it's blue or green). This is syllabus is tentative, last revised , and will almost surely be superceded- RELOAD your browser for the current version.
