d_gaming

<p>The Gaming Platforms dataset (<code>d_gaming</code>) collects the results of a survey conducted on a sample of \(N=91\) Dutch students, who were asked to rank \(K=6\) gaming platforms in order of preference, namely: 1 = X-Box, 2 = PlayStation, 3 = PSPortable, 4 = GameCube, 5 = GameBoy and 6 = Personal Computer. The dataset is composed of complete orderings.</p>

datasets

Fit finite mixtures of Plackett-Luce models for partial top rankings/orderings within the Bayesian framework. It provides MAP point estimates via EM algorithm and posterior MCMC simulations via Gibbs Sampling. It also fits MLE as a special case of the noninformative Bayesian analysis with vague priors. In addition to inferential techniques, the package assists other fundamental phases of a model-based analysis for partial rankings/orderings, by including functions for data manipulation, simulation, descriptive summary, model selection and goodness-of-fit evaluation. Main references on the methods are Mollica and Tardella (2017) <doi.org/10.1007/s11336-016-9530-0> and Mollica and Tardella (2014) <doi/10.1002/sim.6224>.
