Estimating IRT Parameters using the IRT Methodology
An implementation of the IRT paradigm for the scoring of different
instruments measuring latent traits (a.k.a Abilities) and estimating item
parameters for a variety of models, this package is highly optimized using
Rcpp and carefully written R for the rest of the package, it aims to expand IRT
applications to those applications that require faster and more robust estimation
procedures. See the IRTpp documentation and github site for more information and
examples.
