712—Mathematical Statistics I (3) (Prereq: Advanced calculus or consent of instructor) Sample spaces, probability and conditional probability, independence, random variables, expectation, distribution theory, sampling distributions, laws of large numbers and asymptotic theory, order statistics, and estimation.

Usually Offered: Fall Semesters

Purpose: To acquaint beginning graduate students in statistics and other disciplines with the concepts of probability and the mathematical development of statistics. To provide a foundation for further study in probability theory and statistical theory at both the master's and doctoral levels.
