Research Activities

Keywords:
Mixture Models; Composite Likelihood; Latent Variable Models; EM algorithm; Ordinal data.

Brief description:
- Finite mixture models (and some extensions) used mainly for a clustering purpose
- Methodological aspects mainly focused on finite mixture models (the unboundedness of the likelihood for mixture of Gaussians, identifiability issues of mixture models based on an URV approach along with composite likelihood function
- Estimation methods based on composite likelihood and Monte Carlo likelihood
- Different real data applications (ChIP-seq data, marine currents, wildfires, social and behavioral data, time series, three-way data)
