Parameter Estimation of the Reduced RUM Using the EM Algorithm

Diagnostic classification models (DCMs) are psychometric models widely discussed by researchers nowadays because of their promising feature of obtaining detailed information on students’ mastery on specific attributes. Model estimation is essential for further implementation of these models, and est...
