Psychometric Mixture Models R package psychomix version 1.1-10 CRAN Task View: Cluster (https://CRAN.R-project.org/view=Cluster) CRAN Task View: Psychometrics (https://CRAN.R-project.org/view=Psychometrics) Psychometric mixture models based on 'flexmix' infrastructure. At the moment Rasch mixture models with different parameterizations of the score distribution (saturated vs. mean/variance specification), Bradley-Terry mixture models, and MPT mixture models are implemented. These mixture models can be estimated with or without concomitant variables. See Frick et al. (2012) <doi:10.18637/jss.v048.i07> and Frick et al. (2015) <doi:10.1177/0013164414536183> for details on the Rasch mixture models.
