Alice sighed wearily. ‘I think you might do something better with the time,’ shesaid, ‘than waste it in asking riddles that have no answers.’‘If you knew Time as well as I do,’ said the Hatter, ‘you wouldn’t talk aboutwasting IT. It’s HIM.’‘I don’t know what you mean,’ said Alice.‘Of course you don’t!’ the Hatter said, tossing his head contemptuously. ‘I daresay you never even spoke to Time!’‘Perhaps not,’ Alice cautiously replied: ‘but I know I have to beat time when Ilearn music.’‘Ah! that accounts for it,’ said the Hatter. ‘He won’t stand beating.’

Syllabus III

PrerequisitesSTA 4322 (an introductory statistics course) and a basic computer languageare the prerequisites.Topics CoveredWe will (try to) go over most of the textbook. This includes the followingtopics:

Characteristics of Time SeriesTime Series Regression and Exploratory Data AnalysisARIMA ModelsSpectral Analysis and FilteringAdditional Time Domain TopicsState-Space ModelsMethods in the Frequency Domain

SoftwareWe will be using the free, yet powerful, statistics software package R. Rwill be used in your homework and in the lectures, and you will be testedon R’s commands and output at the end of the class.
