Classification of Events Using Local Pair Correlation Functions for Spatial Point Patterns
González, Jonatan A.; Rodríguez-Cortés, Francisco Javier; Romano, Elvira; Mateu, Jorge American Statistical Association (2021-05-12)Spatial point pattern analysis usually concerns identifying features in an observation window where there is also noise. This identification traditionally begins with studying the second-order properties of the point ... -
Heteroskedastic geographically weighted regression model for functional data
Romano, Elvira; Mateu, Jorge; Butzbach, O. Elsevier (2020)A large number of approaches for modelling spatially dependent functional variables often assume that the functional regression coefficients are constant over the region of interest. However, in many occasions it is far ... -
High leverage detection in general functional regression models with spatially correlated errors
Romano, Elvira; Giraldo, Ramón; Mateu, Jorge; Diana, Andrea Wiley (2021)The presence of curves that deviate markedly from the core of a set of curves can greatly affect inference and forecasting in a functional regression model. Thus their detection is key to increase the accuracy of the ... -
On some descriptive and predictive methods for the dynamics of cancer growth
Vlad, Iulian T.; Mateu, Jorge; Romano, Elvira Alma Mater Studiorum - Università di Bologna (2015-01)Cancer is a widely spread disease that affects a large proportion of the human population, and many research teams are developing algorithms to help medics to understand this disease. In particular, tumor growth has been ... -
On the performance of two clustering methods for spatial functional data
Romano, Elvira; Mateu, Jorge; Giraldo, Ramón Springer Verlag (2015-10)The performance of two clustering strategies for spatially correlated functional data based on the same measure of spatial dependence is examined and compared. In particular, the role of the spatial dependence computed by ...
