A Comparison of Two MCMC Algorithms for the 2PL IRT Model

Springer Proceedings in Mathematics and Statistics, 2017
Markov chain Monte Carlo (MCMC) techniques have become popular for estimating item response theory (IRT) models. The current development of MCMC includes two major algorithms: Gibbs sampling and the No-U-Turn sampler (NUTS), which can be implemented in two specialized software packages JAGS and Stan, respectively.

Person Specific Parameter Heterogeneity in the 2PL IRT Model

Multivariate Behavioral Research, 2023
Following Kelderman and Molenaar's demonstration that a factor model with person specific factor loadings is almost indistinguishable from the standard factor model in terms of overall fit, we examined person specific measurement models in Item Response Theory, person specific discrimination and difficulty parameters were created by adding random ...

Using Lasso and Adaptive Lasso to Identify DIF in Multidimensional 2PL Models

Multivariate Behavioral Research, 2022
Differential item functioning (DIF) analysis refers to procedures that evaluate whether an item's characteristic differs for different groups of persons after controlling for overall differences in performance. DIF is routinely evaluated as a screening step to ensure items behave the same across groups.
