Prevalence Analysis of Recurrent and Transient Health States in Quality of Life Studies

  • Andrew Kramar
  • Remi Lancar


We present methods for analyzing quality of life data through the use of weighted prevalence functions when data allow a classification of scores into discrete states of health. Individual longitudinal data is transformed from an event history model into a non-parametric setting to provide a simpler interpretation in terms of probabilities. We discuss similarities and differences with quality adjusted survival methodology and illustrate the methods with an example.
