Details

The immer package has following features:

• Estimation of the hierarchical rater model (Patz et al., 2002) with immer_hrm and simulation of it with immer_hrm_simulate.

• The linear logistic partial credit model as an extension to the linear logistic test model (LLTM) for dichotomous data can be estimated with conditional maximum likelihood (Andersen, 1995) using immer_cml.

• The linear logistic partial credit model can be estimated with composite conditional maximum likelihood (Varin, Reid & Firth, 2011) using the immer_ccml function.

• The linear logistic partial credit model can be estimated with a bias-corrected joint maximum likelihood method (Bertoli-Barsotti, Lando & Punzo, 2014) using the immer_jml function.

• Wrapper function immer_FACETS to the commercial program FACETS (Linacre, 1999) for analyzing multi-faceted Rasch models.
