972/CSI 972 Mathematical Statistics I (3:3:0). Prerequisite: STAT 652 or equivalent. A focus on the theory of estimation. The principles of estimation are explored, including the method of moments, least squares, maximum likelihood, and maximum entropy methods. The methods of minimum variance unbiased estimation are covered in detail. Topics include sufficiency and completeness of statistics, Fisher information, Cramer-Rao bounds, Bhattacharyya bounds, asymptotic consistency and distributions, statistical decision theory, minimax and Bayesian decision rules, and applications to engineering and scientific problems.

973/CSI 973 Mathematical Statistics II (3:3:0). Prerequisite: INFT 972. Continuation of INFT 972. A concentration on the theory of hypothesis testing. Topics include characterizing the decision process, simple versus simple hypothesis tests, Neyman-Pearson Lemma, uniformly most powerful tests, unbiasedness of tests, invariance of tests, randomized tests, and sequential tests. Applications of the testing principles are made to situations in the normal distribution family and to other families of distributions.

976/CSI 976 Statistical Inference for Stochastic Processes (3:3:0). Prerequisite: INFT 746/CSI 776. The modern theory of parameter estimation and hypothesis testing for stochastic processes, counting processes with random intensities, and solutions to stochastic differential equations driven by martingales. Applications to engineering, biology, and economics are considered.

978/CSI 978 Statistical Analysis of Signals (3:3:0). Prerequisites: STAT 544 and 658 or equivalent. An advanced course in the analysis of discrete- and continuous-time signals using methods of stochastic differential equations and time series. . Familiarity with the methods of harmonic analysis and times series modeling is presumed. Topics include state-space modeling and eigen-value processing, nonlinear modeling of signals, non-Gaussian stochastic process structure, detection and estimation of vector-valued signals, robust signal detection, with applications to array processing, and target tracking.

979/CSI 979 Topics in Statistical Aspects of Information Technology (3:3:0). Prerequisite: STAT 652 or equivalent. A study of statistical science¬the body of methods and techniques that convert raw data into information. Contents vary. Such topics as high-interaction statistical graphics, stochastic methods for parallel computing, cryptography and covert communications, order-restricted inference, treatments of imprecision, and the foundations of inference are covered. May be repeated when topics are distinctly different.

980 Advanced Topics in Applied Probability (3:3:0). Prerequisite: OR 645, 647, or permission of instructor depending on the topic(s) for the semester. Special topics and recent developments in the field of applied probability. Contents vary and possible topics include computational probability, stochastic point processes, advanced queueing theory, traffic and transportation models, percolation, processes of random aggregation and coagulation, and Markov decision processes. May be repeated for credit when topics are distinctly different.

984 Advanced Topics in Network Optimization (3:3:0). Prerequisite: OR 643. Recent developments in solving optimization problems on networks. The course prepares doctoral students to perform advanced research on network-related problems. Topics include linear, discrete, nonlinear, and stochastic problems. Several aspects of these problems are also studied. These include but are not limited to computational complexity, exact algorithms, heuristics, solvable special cases, and computer implementation issues.

990 Dissertation Topic Presentation (1:0:0). Prerequisite: Completion of all course requirements for Ph.D. in INFT or permission of instructor. An opportunity for Ph.D. Students to present their research proposal for critique to interested faculty and students. The course covers the presentation of the research topic for the Ph.D. in Information Technology, and is required of all Ph.D. Students. At the end of the course, the student will have completed the dissertation research proposal. The course may be repeated with a change in topic, although degree credit is given once.

998 Doctoral Dissertation Proposal (1-12:0:0). Work on a research proposal that forms the basis for a doctoral dissertation. May be repeated. No more than 24 credit hours of INFT 998 and 999 may be applied to doctoral degree requirements.

999 Doctoral Dissertation (1-12). Prerequisite: Admission to candidacy. A formal record of commitment to doctoral dissertation research under the direction of a faculty member in information technology. May be repeated as needed.
