Soprano voices in opera seria: a corpus-based inquiry into eighteenth-century vocal types
Ana Llorens, Eduardo García-Portugués, Carlos Vaquero +1
Eighteenth-century Italian opera seria was dominated by soprano voices. Although masculine roles were typically performed by castrati and feminine roles by women, cross-casting was…
Optimizing Feature Extraction for Symbolic Music
Federico Simonetta, Ana Llorens, Martín Serrano +2
This paper presents a comprehensive investigation of existing feature extraction tools for symbolic music and contrasts their performance to determine the set of features that best…
Testing for linearity in scalar-on-function regression with responses missing at random
Manuel Febrero-Bande, Pedro Galeano, Eduardo García-Portugués +1
A goodness-of-fit test for the Functional Linear Model with Scalar Response (FLMSR) with responses Missing at Random (MAR) is proposed in this paper. The test statistic relies on a…
On new omnibus tests of uniformity on the hypersphere
Alberto Fernández-de-Marcos, Eduardo García-Portugués
Two new omnibus tests of uniformity for data on the hypersphere are proposed. The new test statistics exploit closed-form expressions for orthogonal polynomials, feature tuning par…
Toroidal PCA via density ridges
Eduardo García-Portugués, Arturo Prieto-Tirado
Principal Component Analysis (PCA) is a well-known linear dimension-reduction technique designed for Euclidean data. In a wide spectrum of applied fields, however, it is common to…
Optimal stopping of Gauss-Markov bridges
Abel Azze, Bernardo D'Auria, Eduardo García-Portugués
We solve the non-discounted, finite-horizon optimal stopping problem of a Gauss-Markov bridge by using a time-space transformation approach. The associated optimal stopping boundar…
Optimal exercise of American options under time-dependent Ornstein-Uhlenbeck processes
Abel Azze, Bernardo D'Auria, Eduardo García-Portugués
We study the barrier that gives the optimal time to exercise an American option written on a time-dependent Ornstein--Uhlenbeck process, a diffusion often adopted by practitioners…
Data-driven stabilizations of goodness-of-fit tests
Alberto Fernández-de-Marcos, Eduardo García-Portugués
Exact null distributions of goodness-of-fit test statistics are generally challenging to obtain in tractable forms. Practitioners are therefore usually obliged to rely on asymptoti…
Scaled torus principal component analysis
Pavlos Zoubouloglou, Eduardo García-Portugués, J. S. Marron
A particularly challenging context for dimensionality reduction is multivariate circular data, i.e., data supported on a torus. Such kind of data appears, e.g., in the analysis of…
Optimal stopping of an Ornstein-Uhlenbeck bridge
Abel Azze, Bernardo D'Auria, Eduardo García-Portugués
We make a rigorous analysis of the existence and characterization of the free boundary related to the optimal stopping problem that maximizes the mean of an Ornstein--Uhlenbeck bri…
