On uniqueness of the set of k-means
Javier Cárcamo, Antonio Cuevas, Luis A. Rodríguez
We provide necessary and sufficient conditions for the uniqueness of the k-means set of a probability distribution. This uniqueness problem is related to the choice of k: depending…
Tests for almost stochastic dominance
Amparo Baíllo, Javier Cárcamo, Carlos Mora-Corral
We introduce a 2-dimensional stochastic dominance (2DSD) index to characterize both strict and almost stochastic dominance. Based on this index, we derive an estimator for the mini…
A uniform kernel trick for high-dimensional two-sample problems
Javier Cárcamo, Antonio Cuevas, Luis-Alberto Rodríguez
We use a suitable version of the so-called "kernel trick" to devise two-sample (homogeneity) tests, especially focussed on high-dimensional and functional data. Our proposal entail…
Extremal points of Lorenz curves and applications to inequality analysis
Amparo Baíllo, Javier Cárcamo, Carlos Mora-Corral
We find the set of extremal points of Lorenz curves with fixed Gini index and compute the maximal -distance between Lorenz curves with given values of their Gini coefficients.…
Directional differentiability for supremum-type functionals: statistical applications
Javier Cárcamo, Luis-Alberto Rodríguez, Antonio Cuevas
We show that various functionals related to the supremum of a real function defined on an arbitrary set or a measure space are Hadamard directionally differentiable. We specificall…
