Functions providing an easy and intuitive way for fitting and clusters data using the Mixture of Unigrams models by means the Expectation-Maximization algorithm (Nigam, K. et al. (2000). doi:10.1023/A:1007692713085), Mixture of Dirichlet-Multinomials estimated by Gradient Descent (Anderlucci, Viroli (2020) doi:10.1007/s11634-020-00399-3) and Deep Mixture of Multinomials whose estimates are obtained with Gibbs sampling scheme (Viroli, Anderlucci (2020) doi:10.1007/s11222-020-09989-9). There are also functions for graphical representation of clusters obtained.
