We develop a latent variable selection method for multidimensional item response theory models. The proposed method identifies latent traits probed by items of a multidimensional test. Its basic strategy is to impose an L1 penalty term to the log-likelihood. The computation is carried out by the expectationmaximization algorithm combined with the coordinate descent algorithm. To the authors’ be...
