IRTpp: 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.
