CoModes package for correlated categorical variables

Participants : Christophe Biernacki, Matthieu Marbac Lourdelle, Vincent Vandewalle.

CoModes is an R package for model-based clustering of categorical data. In this package, the Conditional Modes Model (CMM), published in 2016 (Marbac et al, 2016), takes into account the main conditional dependencies between variables through particular modality crossings (so-called modes). CoModes performs the model selection and provides the best model according to the exact integrated likelihood criterion and the maximum likelihood estimates. It is available online on Rforge (https://r-forge.r-project.org/R/?group_id=1809).
