Nonparametric Cognitive Diagnosis When Attributes are Polytomous

• In Event: Cognitive Diagnostic Models I

Abstract

Within cognitive diagnosis models, attributes are typically perceived as binary. However, polytomous attributes may yield higher precision in the assessment of examinees’ attribute mastery. This study proposed a nonparametric method for cognitive diagnosis for use with polytomous attributes, called the “Nonparametric Polytomous Attributes Diagnostic Classification” (NPADC) method.
