ItemResponseTrees: IR-Tree Modeling in 'mirt', 'Mplus', or 'TAM'

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 Böckenholt (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.
