A Hierarchical Item Response Model for Cognitive Diagnosis
Mark Hansen and Li Cai
The presentation is about diagnostic classification models that are hirearchial in the factor analytic sense (having independent tiers or layers). Or, alternatively, hirearchial item factor analysis models in which the latent variables in the primary tier are discrete rather than continuous.
