Model-Based Co-clustering for Ordinal Data

Participants : Christophe Biernacki, Julien Jacques.

A model-based coclustering algorithm for ordinal data is presented. This algorithm relies on the latent block model using the BOS model (Biernacki and Jacques, 2015, Stat. Comput.) for ordinal data and a SEM-Gibbs algorithm for inference. Numerical experiments on simulated data illustrate the efficiency of the inference strategy. This work has been presented to an international workshop [30] and also to a national conference with an international audience [35].
