datasets


Supplementary item response theory models to complement existing
functions in R, including multidimensional compensatory and
noncompensatory IRT models, MCMC for hierarchical IRT models and
testlet models, NOHARM, Rasch copula model, faceted and
hierarchical rater models, ordinal IRT model (ISOP),
DETECT statistic, local structural equation modeling (LSEM),
mean and covariance structure modelling for multivariate normally
distributed data.
