The MIXMOD software

The MIXMOD (MIXture MODelling) software fits mixture models (Gaussian, Bernoulli, multinomial) to a given data set described by continuous or categorical variables with either a clustering or a discriminant analysis purpose. It is publicly available under the GPL license and is distributed for different platforms (Linux, Unix, Windows). It is developed jointly by INRIA Saclay Île-de-France (SELECT project), the laboratory of mathematics of Besançon, the laboratory of Mathematics of University Lille 1 and the Heudiasyc laboratory of Compiègne.

The software, the statistical documentation and also the userguide are available HERE on the internet.

Other softwares

  • The blockcluster package blockcluster is a R package for model-based simultaneous clustering of rows and columns. It is available online on CRAN HERE for all major platforms (Linux, MacOS, Windows). This package allows to co-cluster binary, contingency and continuous data. It also comes with utility functions to visualize the data. This package is developed by INRIA ( mΘdal team) in collaboration with University of Technology of Compiègne. A short tutorial for the package can be downloaded from here.
  • The rankclust package rankclust is a R package for model-based clustering of partial multivariate rank data. It is available online HERE . This package is developed by INRIA ( mΘdal team). A description of the underlying model is available in the technical paper Preprint HAL n°00743384.
