Item response tree (IR-tree) models are a class of item response
theory (IRT) models that assume that the responses to polytomous items can
best be explained by multiple psychological processes; see B<c3><b6>ckenholt
(2012) <doi:10.1037/a0028111> for details. The package
'ItemResponseTrees' allows to fit such IR-tree models in 'mirt', 'Mplus', or
'TAM'. The package automates some of the hassle of IR-tree modeling by means
of a consistent syntax. This allows new users to quickly adopt this model
class, and this allows experienced users to fit many complex models
effortlessly.
