Psychometric mixture models based on flexmix
infrastructure. At the moment only Rasch mixture models are
implemented in various flavors: with/without concomitant
variables, different parametrizations of the score distribution
(saturated vs. mean/variance specification). See
vignette("raschmix", package = "psychomix") for details.

Psychometric mixture models based on flexmix
infrastructure. At the moment Rasch mixture models with
different parametrizations of the score distribution (saturated
vs. mean/variance specification) and Bradley-Terry mixture
models are implemented. Both mixture models can be estimated
with or without concomitant variables. See vignette("raschmix",
package = "psychomix") for details on the Rasch mixture models.
