This event is being organized by the NCME Diagnostic Measurement SIGIMIE.
This workshop aims to equip participants with practical experience in using cognitive diagnosis models (CDMs) in applied settings. Participants will work with real datasets from various fields such as education, psychology, and social sciences. They will learn to use the GDINA R package for a range of CDM analyses, including model specification, estimation, and evaluation. Some theoretical foundations for these analyses will also be discussed to ensure proper understanding and application of CDMs. By the end of the workshop, participants will have the skills to conduct various CDM analyses and apply these methods to their own research.
This workshop is designed for individuals who have some familiarity with CDMs and want to enhance their skills in using R for CDM analyses. By the end of the session, participants will be able to conduct a range of CDM analyses using the GDINA package.
