A multidimensional latent class IRT model for non-ignorable missing responses
Silvia Bacci, Francesco Bartolucci
We propose a structural equation model, which reduces to a multidimensional latent class item response theory model, for the analysis of binary item responses with non-ignorable mi…
A multilevel finite mixture item response model to cluster examinees and schools
