WebbPolytomous MFC items are less well understood. To the best of our knowledge, only one model (Brown & Maydeu-Olivares, 2024), which is an extension of the Thurstonian IRT model (Brown & Maydeu-Olivares, 2011) for ordinal preference data, treats the categories as ordinal responses.Thus, the present study aims to develop a new IRT model for … Webb1 apr. 2015 · This model expands further the collection of Thurstonian models already available for many discrimination, rating and ranking methodologies.
