R packages

  • cellGMM
    Author and Maintainer
    Gaussian Mixture Model with cellwise outlier detection via the EM algorithm.
    Github.

  • MissUGMM
    Author and Maintainer
    Ultrametric Gaussian Mixture Model able to handle Missing data, estimated via the Expectation-Maximization algorithm which effectively takes this additional source of missingness into account.
    Github.

  • PUGMM
    Author and Maintainer
    Model-based clustering with parsimonious ultrametric covariance structures. The thirteen models implemented allow for the inspection of different hierarchical relationships among variables within clusters.
    CRAN - Github.

  • UFA
    Author and Maintainer
    Ultrametric Factor Analysis to detect hierarchies of nested latent factors underlying multidimensional phenomena. UFA is estimated via a cycling block coordinate descent algorithm.
    Github.
