mixRasch: Mixture Rasch Models with JMLE
The included function will estimate a mixture Rasch model using joint maximum likelihood estimation (JMLE). The estimation is based on a mixture partial credit model. Step parameters can be constrained to estimate a mixture rating scale model. Estimating a model with only one latent class accomplishes a standard Rasch analysis with JMLE.
