On September 25-26, I will present a two-day seminar on Longitudinal
Data Analysis at the Club Quarters Hotel in Chicago, IL. This course
focuses on using SAS to do regression analysis of panel data--the most
common type of longitudinal data--consisting of measurements of
predictor and response variables at two or more points in time for
many individuals.  Early-bird registration ends August 1.

Panel data have two major attractions: the ability to control for
unobservables, and the determination of causal ordering. However,
repeated measurements typically violate assumptions of independence.
This course covers four methods for dealing with dependent
observations:  robust standard errors, generalized estimating
equations, random effects models and fixed effects models. Different
variations of these methods are considered for quantitative outcomes,
categorical outcomes, and count data outcomes.

The course is based in part on my book, "Fixed Effects Regression
Methods for Longitudinal Data Using SAS," published by the SAS
Institute in 2005. SAS will be used for the many empirical examples,
but lecture notes using Stata are also available to participants.

The fee of $750 includes all course materials and a continental
breakfast each day. If you register before August 1, the fee is
discounted to $650. The course will be held at the Club Quarters
Hotel, 111 West Adams St., Chicago, IL  60603.  Guest rooms are
available at the hotel at a special rate.
