Description:
Functions for cognitive diagnosis modeling and multidimensional item response modeling
for dichotomous and polytomous item responses. This package enables the estimation of
the DINA and DINO model (Junker & Sijtsma, 2001, ),
the multiple group (polytomous) GDINA model (de la Torre, 2011,
), the multiple choice DINA model (de la Torre, 2009,
), the general diagnostic model (GDM; von Davier, 2008,
), the structured latent class model (SLCA; Formann, 1992,
) and regularized latent class analysis
(Chen, Li, Liu, & Ying, 2017, ).
See George, Robitzsch, Kiefer, Gross, and Uenlue (2017)
or Robitzsch and George (2019, )
for further details on estimation and the package structure.
For tutorials on how to use the CDM package see
George and Robitzsch (2015, ) as well as
