Accelerating L(1)-penalized expectation maximization algorithm for latent variable selection in multidimensional two-parameter logistic models
One of the main concerns in multidimensional item response theory (MIRT) is to detect the relationship between observed items and latent traits, which is typically addressed by the exploratory analysis and factor rotation techniques. Recently, an EM-based L(1)-penalized log-likelihood method (EML1)...
