abstract: Package to fit diffusion-based IRT models to response and response time
  data. Models are fit using marginal maximum likelihood. Parameter restrictions (fixed
  value and equality constraints) are possible. In addition, factor scores (person
  drift rate and person boundary separation) can be estimated. Model fit assessment
  tools are also available. The traditional diffusion model can be estimated as well.
