Estimation of a Simple Structure in a Multidimensional IRT Model Using Structure Regularization

Estimation of a Simple Structure in a Multidimensional IRT Model Using Structure Regularization

We develop a method for estimating a simple matrix for a multidimensional item response theory model. Our proposed method allows each test item to correspond to a single latent trait, making the results easier to interpret. It also enables clustering of test items based on their corresponding latent...
