Estimation of Models in a Rasch Family for Polytomous Items and Multiple Latent Variables
The Rasch family of models considered in this paper includes models for polytomous items and multiple correlated latent traits, as well as for dichotomous items and a single latent variable. An R package is described that computes estimates of parameters and robust standard errors of a class of log-...
