Course Overview
This is an advanced course in statistics for the social sciences, with particular emphasis on studying processes and events as they unfold over time. In particular, you will wrestle with the rudiments of 
1. Pure time-series analyses (Box-Jenkins/ARIMA modeling, distributed-lag models, Vector autoregression (VAR), and Cointegration);
2. Pooled cross-sectional time-series analysis;
3. Panel data analysis; and
4. Survival analysis (also known as duration, hazard, or event history models). 

Rapid theoretical advances in political science research, the accumulation of reliable temporal data, the abundance of user-friendly statistical packages (for e.g., RATS; STATA; SPSS; LIMDEP; and EVIEWS), and a yen to minimize slippage between theory building and theory testing are forcing political scientists to recognize the shortcomings of static models. However, those who recognize the limitations (and, more important, the misspecification) of static models are few and far in-between. Consequently, this course is your portal to the frontiers of empirical political science research. However, because frontiers are by definition challenging, generally inhospitable domains, be prepared to put in tremendous effort if you wish to master the material. 

If you have any conditions or challenges that may make it difficult for you to meet the requirements of this course or that may leadyou to require extra time on assignments, let me know so that we can make the necessary arrangements.

Texts and Other Requirements
  REQUIRED TEXTS
 
Carefully work through the assigned material before coming to class. You will have to go over the material after class as well to ensure full comprehension. Let me know if you get lost in the material. 

The following texts are mandatory purchases for this course. 
Allison, Paul D. 1984. Event History Analysis: Regression for Longitudinal Event Data. Newbury Park, CA: Sage Publications.
Box-Steffensmeier, Janet M., and Bradford Jones. 2000. Timing and Political Change: Event History Analysis in Political Science. Ann Arbor: University of Michigan Press. (Unpublished; see me)
McCleary, Richard, and Richard A. Hay. 1980. Applied Time Series Analysis for the Social Sciences. Beverly Hills, CA: Sage Publications.
Ostrom, Charles W. 1978. Time Series Analysis: Regression Techniques. Newbury Park, NJ: Sage Publications.

I will assign other readings that will be available to you either in an electronic or in a hardcopy format.  For e.g., a synopsis of Engle & Granger's work on Autoregressive Conditional Heteroscedasticity and Cointegration, respectively. 

You must hold an active on-campus or off-campus email account. I will broadcast answer keys, handouts, and other relevant data via email since it is the speediest mode of communication. In due course of time the website for the course will be up and running and I hope you will utilize this resource as well since I will rely on applets to complement standard instructional technology i.e., the chalk-and-blackboard. The URL for the website, when up and running, will be

  RECOMMENDED TEXTS
There are also a growing number of online statistics texts that explain the innards of statistics in an easy-to-understand manner, using everyday language and examples. A few of the better online statistics texts are linked below. You may be surprised at their usefulness. 
Internet Glossary of Statistical Terms
Statistics at Square One
Introductory Statistics: Concepts, Models, and Applications
The Data Analysis Briefbook
Statistics: The Study of Stability in Variation
Introduction to Probability
Virtual Laboratories in Probability and Statistics
HyperStat Online

  DATA SETS AND CODEBOOKS
From time to time I will provide you with data sets and codebooks. These data will be used either for in-class  exercises and/or homework assignments. When these data are made available you will be able to download them from the relevant area in the Course Calendar (see below)

Grade Requirements
   GRADE COMPOSITION 
The grades you earn in this course are a function of your ability to work hard and to persevere. Practice, practice, and practice; there is no other way known to mankind that bestows thorough understanding of the mechanics underlying the seemingly oblique formulae or, for that matter, how statistical theories shed light on the substantive phenomena of interest to us, researchers. Thus, if you are not prepared to sell your soul to the devil and work hard, drop this course.

 Your grade will be composed of: 
(a)   short focused assignments wherein you will most likely be given a dataset and instructed to apply particular analytic techniques. Carrying equal weight, the assignments will jointly constitute 50 percent of your course grade. 

(b) A theoretically-motivated research paper on a topic of your choosing. However, the paper must involve either pure time series data or some other longitudinal data, with the analytical technique employed guided by the fit of the technique to the theoretical model and data specificities. Presumably this paper will be either a chapter or more in your dissertation or a paper that you hope to present at a conference. The paper contributes 50 percent to your overall grade. 

Note: Late assignments are unacceptable, regardless of the reason behind the delay. If you know you will be unable to make a deadline, obtain my prior approval. 

Course Calendar
Since the emphasis in this course is on giving you a thorough understanding of the rudiments of time-serial anayses, we shall set our own pace. Hence in the calendar below I do not demarcate specific portions of time during which particular topics will be covered.
