A mixed model allows the incorporation of both fixed and random
variables within a statistical analysis. This enables efficient
inferences and more information to be gained from the data. The
application of mixed models is an increasingly popular way of
analysing medical data, particularly in the pharmaceutical
industry. There have been many recent advances in mixed modelling,
particularly regarding the software and applications. This new
edition of a groundbreaking text discusses the latest developments,
from updated SAS techniques to the increasingly wide range of
applications.
* Presents an overview of the theory and applications of mixed
models in medical research, including the latest developments and
new sections on bioequivalence, cluster randomised trials and
missing data.
* Easily accessible to practitioners in any area where mixed
models are used, including medical statisticians and
economists.
* Includes numerous examples using real data from medical and
health research, and epidemiology, illustrated with SAS code and
output.
* Features new version of SAS, including the procedure PROC
GLIMMIX and an introduction to other available software.
* Supported by a website featuring computer code, data sets, and
further material, available at:
http://www.chs.med.ed.ac.uk/phs/mixed/.
This much-anticipated second edition is ideal for applied
statisticians working in medical research and the pharmaceutical
industry, as well as teachers and students of statistics courses in
mixed models. The text will also be of great value to a broad range
of scientists, particularly those working the medical and
pharmaceutical areas.
