Multivariate EDF tests for uniformity, normality,spherical and elliptical symetry, and independence based on a Brownian sheet deconstruction
Alejandra Cabaña, Enrique M. Cabaña
This paper extends a recently proposed family of EDF-based goodness-of-fit procedures for the hypercube - the m-test and the s-test - which are based on a unique deconstr…
The Morgan-Pitman Test of Equality of Variances and its Application to Machine Learning Model Evaluation and Selection
Argimiro Arratia, Alejandra Cabaña, Ernesto Mordecki +1
Model selection in non-linear models often prioritizes performance metrics over statistical tests, limiting the ability to account for sampling variability. We propose the use of a…
Bayesian Synthetic Likelihood Estimation for Underreported Non-Stationary Time Series: Covid-19 Incidence in Spain
David Moriña, Amanda Fernández-Fontelo, Alejandra Cabaña +2
The problem of dealing with misreported data is very common in a wide range of contexts for different reasons. The current situation caused by the Covid-19 worldwide pandemic is a…
Estimating the real burden of disease under a pandemic situation: The SARS-CoV2 case
Amanda Fernández-Fontelo, David Moriña, Alejandra Cabaña +2
The present paper introduces a new model used to study and analyse the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) epidemic-reported-data from Spain. This is a Hidd…
Cumulated burden of Covid-19 in Spain from a Bayesian perspective
David Moriña, Amanda Fernández-Fontelo, Alejandra Cabaña +3
The main goal of this work is to estimate the actual number of cases of Covid-19 in Spain in the period 01-31-2020 / 06-01-2020 by Autonomous Communities. Based on these estimates,…
Quantifying the under-reporting of genital warts cases
David Moriña, Amanda Fernández-Fontelo, Alejandra Cabaña +4
Genital warts are a common and highly contagious sexually transmitted disease. They have a large economic burden and affect several aspects of quality of life. Incidence data under…
New statistical model for misreported data with application to current public health challenges
David Moriña, Amanda Fernández-Fontelo, Alejandra Cabaña +1
The main goal of this work is to present a new model able to deal with potentially misreported continuous time series. The proposed model is able to handle the autocorrelation stru…
Permutation tests in the two-sample problem for functional data
Alejandra Cabaña, Ana Maria Estrada, Jairo I. Peña +1
Three different permutation test schemes are discussed and compared in the context of the two-sample problem for functional data. One of the procedures was essentially introduced b…
Modeling stationary data by a class of generalised Ornstein-Uhlenbeck processes
Argimiro Arratia, Alejandra Cabaña, Enrique M. Cabaña
An Ornstein-Uhlenbeck (OU) process can be considered as a continuous time interpolation of the discrete time AR process. Departing from this fact, we analyse in this work the…
Tracing the temporal evolution of clusters in a financial stock market
Argimiro Arratia, Alejandra Cabaña
We propose a methodology for clustering financial time series of stocks' returns, and a graphical set-up to quantify and visualise the evolution of these clusters through time. The…
