Data from studies with repeated measurement in general are incomplete due to drop out. We will use terminology of little and Rubin (1987, Chapter 6) for the missing-value process. longitudinal data, which features measurements that are repeatedly taken on subjects at several points in time. The previous article discusses a response-profile analysis, which uses an ANOVA method to determine differences between the means of an experimental group and a placebo group. The response-profile analysis has limitations, including the fact that longitudinal data are autocorrelated and so do not satisfy the independence assumption of ANOVA.

But I cannot work out … Longitudinal Data and SAS details useful techniques for conducting operations between observations in a SAS data set. For quick reference, the book is conveniently organized to cover tools-an introduction to powerful SAS programming techniques for longitudinal data; case studies-a variety of illuminating examples that use Ron's techniques; and macros-detailed descriptions of helpful His newest Book by Users Press titled Longitudinal Data and SAS: A Programmer's Guide, offers new and intermediate users, working with longitudinal data, the basic tools for success.
