Title: "Latent Class and Latent Factor Models for Item Response Data"
Abstract:
This talk focuses on two classes of statistical models for item response data which often arise from educational assessment and psychological measurement. The first one is the class of multidimensional item response theory models and the second one is the Q-matrix based class of diagnostic classification models. Recent developments on these models and their extensions will be discussed. Applications to several data sets will also be presented.
