For analyzing item response data, item response theory (IRT) models treat the discrete responses to the items as driven … response patterns. Researchers have been connecting the two paradigms by establishing equivalence relationships between IRT … models and log-linear models. This has lead to the notion of obtaining IRT solutions by fitting their equivalent log …
