  "Description": "Fit finite mixtures of Plackett-Luce models for partial\ntop rankings/orderings within the Bayesian framework. It\nprovides MAP point estimates via EM algorithm and posterior\nMCMC simulations via Gibbs Sampling. It also fits MLE as a\nspecial case of the noninformative Bayesian analysis with vague\npriors. In addition to inferential techniques, the package\nassists other fundamental phases of a model-based analysis for\npartial rankings/orderings, by including functions for data\nmanipulation, simulation, descriptive summary, model selection\nand goodness-of-fit evaluation.
