A local correlation integral method for outlier detection in spatially correlated functional data
Springer (2023)This paper proposes a new methodology for detecting outliers in spatially correlated functional data. We use a Local Correlation Integral (LOCI) algorithm substituting the Euclidean distance calculation by the Hilbert space ... -
A second order approach to analyse spatial point patterns with functional marks
Springer (2011-11)A new second order statistic based on the mark correlation function to analyse spatial point patterns with functional marks is presented. An edge corrected estimator is defined and illustrated through a ... -
Archetypoid analysis for sports analytics
Springer Verlag (2017-06)We intend to understand the growing amount of sports performance data by finding extreme data points, which makes human interpretation easier. In archetypoid analysis each datum is expressed as a mixture of actual observations ... -
Functional archetype and archetypoid analysis
Elsevier (2016-12)Archetype and archetypoid analysis can be extended to functional data. Each function is approximated by a convex combination of actual observations (functional archetypoids) or functional archetypes, which are a convex ... -
Hippocampal shape analysis in Alzheimer’s disease using Functional Data Analysis
Wiley-Blackwell (2013)The hippocampus is one of the first affected regions in Alzheimer's disease. The left hippocampi of control subjects, patients with mild cognitive impairment and patients with Alzheimer's disease are represented by spherical ... -
On using Reproducing Kernel Hilbert Spaces for the analysis of Replicated Spatial Point Processes
Elsevier (2023)This paper focuses on the use of the theory of Reproducing Kernel Hilbert Spaces in the statistical analysis of replicated point processes. We show that spatial point processes can be observed as random variables in a ...
