my current research consists of:
Unbiased mixed-variable distance (van de Velden, M., Iodice D’Enza, A., Markos, A. and Cavicchia, C.) - Under review - arXiv - SSRN
Convex Clustering of Mixed Numerical and Categorical Data (Brink, T. and Cavicchia, C.)
Sparse Scaling (Groenen, P.J.F. and Cavicchia, C.)
Exact solutions for the Sparse Clustering Problem (Soer, M., Cavicchia, C., Kuryatnikova, O. and van den Heuvel, W.)
A Supervised Distance Metric for K-Nearest Neighbors with Mixed-Type Data (van de Velden, M., Iodice D’Enza, A., Markos, A. and Cavicchia, C.)
Modeling Response Styles Across Respondents and Items in Ordinal Questionnaire Data (D’Ambrosio, A., van de Velden, M., Cavicchia, C. and D’Ambrosio, A.)
When Financial Structures Become Misaligned: Diagnosing Persistent Default Risk through Configurational Signals (Ariante, I., Sarnacchiaro, P. and Cavicchia, C.)
Structural equation modeling with block covariance structure (Alfons, A. and Cavicchia, C.)
Clustering combining two sources of information: dissimilarities and features on the same observations (Cavicchia, C., van de Velden, M. and Vichi, M.)
Model-based Parsimonious Hierarchical Clustering (Cavicchia, C., Chirita, A. and Scrucca, L.)
Higher-order Factor Analysis (Cavicchia, C. and Vichi, M.)
