713—Mathematical Statistics II (3) (Prereq: STAT 712) Further development of estimation theory and tests of hypotheses, including an introduction to Bayes methods, sufficiency and completeness, minimum variance principles, uniformly most powerful and likelihood ratio tests, consistency and asymptotic efficiency.

Usually Offered: Spring Semesters

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