immer: Item Response Models for Multiple Ratings
Implements some item response models for multiple
ratings, including the hierarchical rater model,
conditional maximum likelihood estimation of linear
logistic partial credit model and a wrapper function
to the commercial FACETS program. See Robitzsch and
Steinfeld (2018) for a description of the functionality
of the package.
See Wang, Su and Qiu (2014; <doi:10.1111/jedm.12045>)
for an overview of modeling alternatives.
