Scoring and Psychometrics
Most LEVANTE measures are scored using item-response theory (IRT) measures. This page documents our modeling approach and decision-making, as well as providing links to code. Note that these pages are actively being updated as the scoring approach is developed.
Our philosophy around measurement and inference is described here.
General Psychometric Model Details
Our general approach is to fit IRT models.
- All model comparison uses the Intermodel Vigorish.
- All IRT models use priors.
FAQ
Do multidimensional IRT models need covariance parameters?
