title: 'irtbem2pl: Marginalized Bayesian Item Parameter Estimation, 2pl Model IRT'
version: 1.0.0
doi: 10.32614/CRAN.package.irtbem2pl
abstract: Estimates item parameters of the two-parameter logistic (2PL) model in Item
  Response Theory (IRT) using the marginal Bayesian modal estimation via the Expectation-Maximization
  (EM) algorithm. The package calibrates item discrimination and difficulty parameters,
  yielding results comparable to software like 'BILOG-MG'.
