Time Series Analysis

Time Series Analysis Genie Baker University of Oregon Course description: This course introduces statistical methods appropriate when sample observations are not independent, but rather, are logically ordered. Coverage will begin with the traditional ARIMA (Box-Jenkins) approach to time series analysis, and proceed through dynamic modeling and regression approaches to recent developments such as cointegration analysis, error correction models, and vector autoregression. Heavy emphasis will be given to fundamental concepts and applied work. Prerequisites for the course include a solid understanding of the fundamentals of statistical inference, regression analysis, matrix algebra, and the general linear model. Course requirements and evaluation: There will be four homework assignments and an exam. Grades will be based on the top 3 homework scores and the exam score, with each receiving equal weight. Homework assignments will include statistical problems and computer assignments requiring the use of statistical software. SAS, Stata, and E-Views will be used for various applications to give students a sense of the comparative strengths and weakness of different packages. Required Texts: Patrick T. Brandt and John T.
