ABSTRACT
Repeated measurements is a term used to describe data in which the
response variable for each experimental unit is observed on multiple occasions
and possibly under different experimental conditions. There are a variety of
disciplines which make use of repeated measurements. Our experiences wi th
repeated measurements are more deeply rooted in applications in the health
and life sciences, epidemiology and biomedical research, and our choice of
examples wi l l reflect this. However, many of the methods presented in this
book can also be applied to other areas including education, psychology, the
social sciences and econometrics (e.g., panel data), as well as to areas of
application involving clustered data and spatial data.
