STATISTICS (STT) STT 5530-5549. Selected Topics/(1-4).On Demand. STT 5820. Design and Analysis of Experiments/(3).F.Odd-numbered years. The course begins with a review of sampling, sampling distributions, and simple comparative experiments. Single factor experiments with both fixed and random effects are considered. Designs illustrated include randomized blocks, latin squares and factorial experiments. Mixed models and rules for expected mean square are presented. Model adequacy, sample size considerations, power determinations and restrictions on randomization procedures are discussed. The use of statistical software packages is integrated throughout the course. Prerequisite: STT 3820 (Statustucak Methods), or permission of instructor. (Dual-listed with STT 4820.) STT 5830. Linear Regression Models/(4).S. An introduction to least squares estimation in simple and multiple regression models. The matrix approach is used in the more general multiple regression model. Considerable attention is given to the analysis of variance, aptness of the model tests, residual analysis, the effects of multicollinearity, and variable selection procedures. Prerequisites: MAT 2240 (Linear Algebra) and STT 3820 (Statistical Methods). (Dual-listed with STT 4830.) STT 5860. Mathematical Statistics I/(3).F. An introduction to the mathematical principles of statistical inference. Topics include a study of sampling theory, point and interval estimation, and hypothesis testing. Prerequisite: STT 4250 (Probability Models) and MAT 2130 (Calculus III). (Dual-listed with STT 4860.) STT 5865. Mathematical Statistics II/(3).S.Odd-numbered years. A study of mathematical statistics to include such topics as sampling distributions, consistency, best asymptotic normal estimators, sufficiency, maximum likelihood estimation, Bayes' estimators, confidence intervals and tests of hypotheses. Prerequisite: STT 5860. (Dual-listed with STT 4865.)
