MixtComp (Mixture Composer) is a model-based clustering package for mixed data originating from the Modal team (Inria Lille).

It has been engineered around the idea of easy and quick integration of all new univariate models, under the conditional independence assumption. New models will eventually be available from researches, carried out by the Modal team or by other teams. Currently, central architecture of MixtComp is built and functionality has been field-tested through industry partnerships. Five basic models (Gaussian, Multinomial, Poisson, Weibull, NegativeBinomial) are implemented, as well as two advanced models (Func_CS and Rank_ISR).

MixtComp has the ability to natively manage missing data (completely or by interval). MixtComp is used as an R package, but its internals are coded in C++ using state of the art libraries for faster computation.

Branches (for MixtComp dev team)

There are two branches tested on the ci server (using the file):

  • master this branch is protected, MixtComp must always work on it.
  • staging this branch is used for short development, testing new features, bug fixes... and its content is regularly pushed to master when tests are OK. Big features should be developed on a specific branch.
You can’t perform that action at this time.
