Functional Clustering of Survival Data via Smoothed Log-Hazard Trajectories: A Risk-Dynamics Perspective
Anna De Magistris, Elvira Romano, Fabrizio Maturo
This paper investigates clustering in survival data by shifting the analytical focus from cumulative survival probabilities to instantaneous risk, as characterized by the hazard fu…
Network Weighted Functional Regression: a method for modeling dependencies between functional data in a network
Elvira Romano, Antonio Irpino, Claire Miller
In this paper, we propose a Network-Weighted Functional Regression (NWFR) model, an extension of Spatially Weighted Functional Regression (SWFR) to functional data defined on netwo…
Conformal prediction for functional Ordinary kriging
Anna De Magistris, Andrea Diana, Elvira Romano
Functional Ordinary Kriging is the most widely used method to predict a curve at a given spatial point. However, uncertainty remains an open issue. In this article a distribution-f…
Roughness regularization for functional data analysis with free knots spline estimation
Anna De Magistris, Valentina De Simone, Elvira Romano +1
In the era of big data, an ever-growing volume of information is recorded, either continuously over time or sporadically, at distinct time intervals. Functional Data Analysis (FDA)…
