Overview

About

Maintained by Maxwell MansolfFirst published 2024-10-041 releasesCRAN page ↗

Allows for multiple group item response theory alignment a la 'Mplus' to be applied to lists of single-group models estimated in 'lavaan' or 'mirt'. Allows item sets that are overlapping but not identical, facilitating alignment in secondary data analysis where not all items may be shared across assessments.
