On the suitability of ratio variables in data envelopment analysis: An application to education with methodological extensions
Vicente J. Bolós, Víctor J. España, Rafael Benítez +1
It is well known that the use of ratio variables is inconsistent with the fundamental assumptions of convex Data Envelopment Analysis (DEA). However, in this paper, we establish a…
Biarchetype analysis for univariate functional data. An application to macroeconomic financial time series
Aleix Alcacer, Rafael Benitez, Vicente J. Bolos +1
We introduce biarchetype analysis for the first time in the context of univariate functional data. This unsupervised methodology extends archetype analysis by simultaneously identi…
Archetypal analysis of European 10-year government bond yields with multidimensional scaling of two-mode three-way asymmetric dissimilarities
Aleix Alcacer, Rafael Benitez, Vicente J. Bolos +1
A recent methodology for extracting archetypal profiles from three-way asymmetric proximity data is applied to a dataset comprising 23 x 23 x 3 two-mode, three-way asymmetric dissi…
Multidimensional scaling of two-mode three-way asymmetric dissimilarities: finding archetypal profiles and clustering
Mireia Mollar-Gumbau, Aleix Alcacer, Rafael Benitez +2
Multidimensional scaling visualizes dissimilarities among objects and reduces data dimensionality. While many methods address symmetric proximity data, asymmetric and especially th…
