Abstract: Identifying item–trait relationships is a core task in multidimensional item response theory (MIRT). Common empirical approaches include exploratory item factor analysis (EIFA) with rotations, the expectation maximization-based L1 regularization (EML1) algorithm, and the expectation model… read more here.
