Description Details Author(s) Examples

This package computes the parameter estimates of a Rasch model for dichotomous and polythomous item responses by using weighted CML estimation, including the possibility of using sampling weights. Procedures to calculate prevalence rates of the phenomenon of interest (latent variable) and to equate item parameters across different context are implemented.
