“…We will briefly compare ten DCMs that are currently capable of handling polytomous item responses, to point out where the RSDM sits in the big picture. These models are (1) the NRDM, (2) the PC-DINA, (3) the general diagnostic model (GDM;von Davier, 2005), (4) the polytomous log-linear cognitive diagnosis model (P-LCDM; Hansen, 2013), (5) the sequential G-DINA model (SG-DINA; Ma & de la Torre, 2016), (6) the DINA model for graded data (DINA-GD; Tu et al, 2017), (7) the general polytomous diagnosis model (GPDM; Chen & de la Torre, 2018), (8) the ordinal response diagnostic model (ORDM; Liu & Jiang, 2018), (9) the modified ordinal response diagnostic model (MORDM; Liu & Jiang, 2018), and (10) the RSDM. We categorize the ten models in Table 14, on the basis of their reduced binary models and polytomous extension features.…”
