• A computational validation for nonparametric assessment of spatial trends 

      Meilán-Vila, Andrea; Fernández-Casal, Rubén; Crujeiras-Casais, Rosa M.; Francisco-Fernández, Mario (2021)
      The analysis of continuously spatially varying processes usually considers two sources of variation, namely, the large-scale variation collected by the trend of the process, and the small-scale variation. Parametric trend ...
    • A Nonparametric Bootstrap Method for Heteroscedastic Functional Data 

      Fernández-Casal, Rubén; Castillo-Páez, Sergio; Flores, Miguel (Springer, 2024-03)
      [Absctract]: The objective is to provide a nonparametric bootstrap method for functional data that consists of independent realizations of a continuous one-dimensional process. The process is assumed to be nonstationary, ...

    • Constructing a Control Chart Using Functional Data 

      Flores, Miguel; Naya, Salvador; Fernández-Casal, Rubén; Zaragoza, Sonia; Raña, Paula; Tarrío-Saavedra, Javier (MDPI AG, 2020-01-02)
      [Abstract] This study proposes a control chart based on functional data to detect anomalies and estimate the normal output of industrial processes and services such as those related to the energy efficiency domain. Companies ...
    • Financialization, confidence, and sovereign debt markets: the role of Credit Default Swaps in the Southern European debt crisis 

      Massó, Matilde; Fernández-Casal, Rubén; Taboadela, Obdulia (Sage, 2022)
      [Abstract] This article analyzes the state–market nexus by examining the role played by sovereign credit default swap (CDS) derivative markets in the southern European debt crisis of 2010–2014. This nexus is conceived of ...
    • Nonparametric Conditional Risk Mapping Under Heteroscedasticity 

      Fernández-Casal, Rubén; Castillo-Páez, Sergio; Francisco-Fernández, Mario (Springer Nature, 2024-03)
      [Absctract]: A nonparametric procedure to estimate the conditional probability that a nonstationary geostatistical process exceeds a certain threshold value is proposed. The method consists of a bootstrap algorithm that ...
    • Nonparametric geostatistical risk mapping 

      Fernández-Casal, Rubén; Castillo-Páez, Sergio; Francisco-Fernández, Mario (2018)
      In this work, a fully nonparametric geostatistical approach to estimate threshold exceeding probabilities is proposed. To estimate the large-scale variability (spatial trend) of the process, the nonparametric local linear ...
    • Statistical Quality Control with the qcr Package 

      Flores, Miguel; Fernández-Casal, Rubén; Naya, Salvador; Tarrío-Saavedra, Javier (Technische Universitaet Wien, 2021)
      [Abstract] The R package qcr for Statistical Quality Control (SQC) is introduced and described. It includes a comprehensive set of univariate and multivariate SQC tools that completes and increases the SQC techniques ...
