Robust Mixture Model
Description
In this package, we provide functions to provide robust clustering in the case of Gaussian, Student and Laplace Mixture Models. Function RobVar computes robustly the covariance of a numerical data set which are realizations of Gaussian, Student or Laplace vectors. Function RobMM enables to provide a clustering of a numerical data set, RMMplot enables to produce graph for Robust Mixture Models, while Gen_MM enables to generate possibly contaminated mixture of Gaussian, Student and Laplace vectors.
