Profile Analysis of Multivariate Data in R

Description

The package eirm provides a set of tools to analyze and visualize dichotomous and polytomous item responses using the explanatory item response modeling (EIRM). The generalized linear mixed modeling (GLMM) framework is used for examining the impact of item-related and person-related variables on responses. The items are repeated measures that are nested underpersons. The model details can be found at de Boeck and Wilson's (2004) Explanatory Item Response Models - A Generalized Linear and Nonlinear Approach <DOI: 10.1007/978-1-4757-3990-9>.
