Rasch Models In Health

the long version

"The family of statistical models known as Rasch models started with a simple model for responses to questions in educational tests presented together with a number of related models that the Danish mathematician Georg Rasch referred to as models for measurement. Since the beginning of the 1950s the use of Rasch models has grown and spread from education to the measurement of health status. This book contains a comprehensive overview of the statistical theory of Rasch models."--Back cover.
