IR-Tree Modeling in 'mirt', 'Mplus', or 'TAM'
Overview
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.
- Fixed tests and vignette that failed due to changes in package mirt version 1.32.1.
augment()now consistently prefixes new columns with.fitted.or.se.fit.. Furthermore, its argumentse.fitwas renamed tose_fit(as recommended by package modeltests).- Uncoupled README from the vignette; README is now much shorter.
- R (>= 3.6.0) is now required in alignment with the dependency mirt.
