Statistical Analysis of Cost-Effectiveness Data

Statistical Analysis of Cost-Effectiveness Data

Andrew R. Willan, Andrew H. Briggs

ISBN: 978-0-470-85628-4 August 2006 210 Pages



The statistical analysis of cost-effectiveness data is becoming increasingly important within health and medical research. Statistical Analysis of Cost-Effectiveness Data provides a practical book that synthesises the huge amount of research that has taken place in the area over the last two decades.

Comprising an up-to-date overview of the statistical analysis of cost-effectiveness data, the book is supported by numerous worked examples from the author’s own experience. It has been written in a style suitable for medical statisticians and health care professionals alike. Key features include:

  • an overview of statistical methods used in the analysis of cost-effectiveness data. 
  • coverage of Bayesian methodology.
  • illustrated throughout by worked examples using real data.
  • suitability for health care professionals with limited statistical knowledge.
  • discussion of software used for data analysis.

An essential reference for biostatisticians and health economists engaged in cost-effectiveness analysis of health-care interventions, both in academia and industry. Also of interest to graduate students of biostatistics, public health and economics.
