If course will be offered on a bi-annual basis, please indicate here: 2.c Student Requirements Students required to take this course: (by program and year, as appropriate) Students who might elect to take the course: Any MS Applied Statistics Students or any other RIT graduate students In the sections that follow, please use sub-numbering as appropriate (eg. 3.1, 3.2, etc.) 3.0 Goals of the course (including rationale for the course, when appropriate): 3.1 Understand the fundamental and crucial difference between time series data and traditional independent and identically distributed samples used in basic statistics 3.2 Learn and master the basic concepts and methods of time series analysis and forecasting to the point of applying them to many real world case studies 3.3 Use a statistical software (Minitab, SAS or R) to perform a complete time series analysis and forecasting on a real world case study and write a complete report of the findings along with well supported recommendations 4.0 Course description (as it will appear in the RIT Catalog, including pre- and corequisites, and quarters offered). Please use the following format: COS-STAT-873 Time Series Analysis and Forecasting This course is designed to provide the student with a solid practical hands-on introduction to the fundamentals of time series analysis and forecasting. Topics include stationarity, filtering, differencing, time series decomposition, time series regression, exponential smoothing, and Box-Jenkins techniques. Within each of these we will discuss seasonal and non-seasonal models. Many real-world examples will be covered and demonstrated using modern statistical software. 2
