emIRT (0.0.5)

EM Algorithms for Estimating Item Response Theory Models.

http://cran.r-project.org/web/packages/emIRT

Various Expectation-Maximization (EM) algorithms are implemented for item response theory (IRT) models. The current implementation includes IRT models for binary and ordinal responses, along with dynamic and hierarchical IRT models with binary responses. The latter two models are derived and implemented using variational EM.
