The Data Science Research Group of the Department of Economics and Business of the University of Catania is formed by researchers working in methodological, applied and computational statistics. Research focuses in the developing of methods and applications related to the extraction of knowledge from either structured or unstructured data. Over the past few years, main research topics have been related to the development of new clustering and classification techniques, mainly in the framework of model-based clustering and mixture models. In this field, the group has produced many papers, published in high-qualified peer-reviewed scientific journals, and software packages for the R platform for statistical computing. Applications have been proposed in medicine, social statistics, population science, marketing and astrophysics as well.
