%description
Various Expectation-Maximization (EM) algorithms are implemented for item
response theory (IRT) models. The package includes IRT models for binary
and ordinal responses, along with dynamic and hierarchical IRT models with
binary responses. The latter two models are fitted using variational EM.
The package also includes variational network and text scaling models.
The algorithms are described in Imai, Lo, and Olmsted (2016)
<DOI:10.1017/S000305541600037X>.
