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.

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.

4 Longitudinal Data and SAS: A Programmer’s Guide Notice that the value of X is missing the first time, but for each additional iteration of the DATA step, it retains the value it had in the previous iteration. Notice that the value of X is missing after the third value of X is read. Data came from 574 Dutch adults aged 75+, collected in five nine-month measurement waves conducted between 2015 and 2018 for the Longitudinal Aging Study Amsterdam.
