Giacomo Lanfiuti Baldi, Andrea Nigri, Han Lin Shang
Understanding and modeling mortality patterns, especially differences in mortality rates between populations, is vital for demographic analysis and public health planning. We compa…
Extending finite mixture models with skew-normal distributions and hidden Markov models for time series
Andrea Nigri, Marco Forti, Han Lin Shang
We introduce an extension of finite mixture models by incorporating skew-normal distributions within a Hidden Markov Model framework. By assuming a constant transition probability…
Null Distance and Temporal Functions
Andrea Nigri
The notion of null distance was introduced by Sormani and Vega as part of a broader program to develop a theory of metric convergence adapted to Lorentzian geometry. Given a time f…
Modelling higher education dropouts using sparse and interpretable post-clustering logistic regression
Andrea Nigri, Massimo Bilancia, Barbara Cafarelli +1
Higher education dropout constitutes a critical challenge for tertiary education systems worldwide. While machine learning techniques can achieve high predictive accuracy on select…
