Description

Since the publication of the first edition the topic of mixed modelling has seen many developments, particularly regarding software and applications. There are now many more software options for applying mixed model methodology, and SAS has been updated to include powerful new techniques. Applications of mixed models have increased, notably in the areas of health research and epidemiology.

This new edition presents:

  • Presents an overview of the theory of mixed models applied to problems in medical research
  • Fully updated to include up-to-date references and developments.
    Computer examples updated to the latest edition of SAS, and now includes more discussion of other software options
  • Includes many more examples using real data, including examples from health research and epidemiology
  • Includes a new section on missing data, and a serious update of the material on repeated measures
  • Supported by a Website featuring computer code, data sets, and further material
