Purpose- This course considers statistical techniques to evaluate social processes occurring through time. The early focus is on econometric regression methods, followed by a Box-Jenkins perspective, with later attention given to approaches such as Error Correction models, multivariate time series (VAR), and State Space modeling. We will also look at time varying parameter models including ARCH and regime switching.  The emphasis throughout the course will be on application, rather than on statistical theory. However, the focus of most lectures will be statistical theory.

It is assumed that you bring to the course a background in high school level algebra and statistics up to and including regression. You should also have some experience with microcomputers. Primary statistical packages for the class will be RATS (WINRATS; MACRATS), STATA, and R. However, you need not be proficient in these before entering the course since sample programs will be provided.

Grades- The course grade will be determined by your performance on the homework assignments and class presentations (33%), a research project in which you apply one or more of the tools presented in this course (33%), and a final examination (33%). Homework is due the next week after the assignment on the following course outline. I will call on each of you at some point to discuss aspects of the homework assignment. The research project is due via email on Wednesday, May 4. Late homework or research projects will not be accepted. The final examination will be take-home, sent out electronically on Wednesday May 4 and due back electronically on Wednesday May 11.

Use RATS, STATA, and R to identify the different ARIMA components of these series using the autocorrelation function and its associated tools. Make sure that you do appropriate transformations of these series to assure level and variance stationarity. In RATS use @URADF, @PPUNIT, @BAYESTST, @KPSS, @ERSTEST, and @VRATIO to do formal hypothesis tests for the level stationarity of these and the transformed series.  Also, visit
Estima’s web site and explore some of the other procedures for determining whether there is a unit root. In STATA, apply some of the alternative procedures for diagnosing stationarity conditions, including dfuller, pperron, dfgls, and kpss.
