A study of alternative approaches to non-normal latent trait distributions in item response theory models used for health outcome measurement
It is often unrealistic to assume normally distributed latent traits in the measurement of health outcomes. If normality is violated, the item response theory (IRT) models that are used to calibrate questionnaires may yield parameter estimates that are biased. Recently, IRT models were developed for...
