Item Response Theory (IRT) is a psychometric approach that focuses both on the subjects’ response to a test item as well as the qualities of the test items. In particular, we focus on the Rasch model for IRT.
jMetrik is more powerful than you may think. It is designed for operational work where researchers need multiple procedures in a single unified framework. Currently you can estimate IRT parameters for the Rasch, partial credit and rating scale models. It also allows for IRT scale linking via the Stocking-Lord, Haebara and other methods.
