Detecting change-points in multivariate settings is usually carried out by analyzing all marginals either independently, via univariate methods, or jointly, through multivariate approaches. The former discards any inherent ... -
Machine learning procedures for daily interpolation of rainfall in Navarre (Spain)
Militino, Ana F. ; Ugarte Martínez, María Dolores ; Pérez Goya, Unai (Springer, 2023)
Capítulo de libro / Liburuen kapitulua
Kriging is by far the most well known and widely used statistical method for interpolating data in spatial random fields. The main reason is that it provides the best linear unbiased predictor and it is an exact interpolator ... -

Elton's near unconditionality of bases as a threshold-free form of greediness
Albiac Alesanco, Fernando José ; Ansorena, José L.; Berasategui, Miguel (Elsevier, 2023)
Artículo / Artikulua
Elton's near unconditionality and quasi-greediness for largest coefficients are two properties of bases that made their appearance in functional analysis from very different areas of research. One of our aims in this note ... -
Scores of hesitant fuzzy elements revisited: "Was sind und was sollen"
Alcantud, José Carlos R.; Campión Arrastia, María Jesús ; Induráin Eraso, Esteban ; Munárriz Iriarte, Ana (Elsevier, 2023)
Artículo / Artikulua
This paper revolves around the notion of score for hesitant fuzzy elements, the constituent parts of hesitant fuzzy sets. Scores allow us to reduce the level of uncertainty of hesitant fuzzy sets to classical fuzzy sets, ... -
