The literature on clustering for continuous data is rich and wide; differently, that one developed for categorical data is still limited. In some cases, the problem is made more difficult by the presence of noise variables/dimensions that do not contain information about the clustering structure and could mask it. The aim of this paper is to propose a model for simultaneous clustering and dimensionality reduction of ordered categorical data able to detect the discriminative dimensions…

Model based clustering of high-dimensional binary data
Model-Based Clustering for Conditionally Correlated Categorical Data
TLDR
An extension of the latent class model is presented for clustering categorical data by relaxing the classical “class conditional independence assumption” of variables to produce a meaningful dependency model with only a few additional parameters.
Mixture models for ordinal data: a pairwise likelihood approach
TLDR
A latent Gaussian mixture model to classify ordinal data is proposed that allows us to overcome the computational problems arising in the full maximum likelihood approach due to the evaluation of multidimensional integrals that cannot be written in closed form.
Simultaneous model-based clustering and visualization in the Fisher discriminative subspace
TLDR
A discriminative latent mixture (DLM) model which fits the data in a latent orthonormal discrim inative subspace with an intrinsic dimension lower than the dimension of the original space is presented.
Finite mixture model of conditional dependencies modes to cluster categorical data.
TLDR
A parsimonious extension of the classical latent class model to cluster categorical data by relaxing the class conditional independence assumption is proposed, which allows to bring out the intra-class dependency between variables and to summarize each class by a few characteristic modality crossings.
Standard and Novel Model Selection Criteria in the Pairwise Likelihood Estimation of a Mixture Model for Ordinal Data
TLDR
This paper proposes some new extensions of the standard criteria based on the expected complete log-likelihood to the non-standard context of a pairwise likelihood approach that is a less demanding and more stable estimation.
Gaussian parsimonious clustering models
A factor mixture analysis model for multivariate binary data
TLDR
A latent variable model for binary data coming from an unobserved heterogeneous population that allows to achieve dimension reduction when the data are dichotomous and performs model based clustering in the latent space is proposed.
