    • Bayesian inference in multivariate spatio-temporal areal models using INLA: analysis of gender-based violence in small areas 

      Vicente, G.; Goicoa Mangado, Tomás Upna; Ugarte Martínez, María Dolores Upna (Springer, 2020)   Artículo / Artikulua  OpenAccess
      Multivariate models for spatial count data are currently receiving attention in disease mapping to model two or more diseases jointly. They have been thoroughly studied from a theoretical point of view, but their use in ...
    • Checking unimodality using isotonic regression: an application to breast cancer mortality rates 

      Rueda, C.; Ugarte Martínez, María Dolores Upna; Militino, Ana F. Upna (Springer, 2016)   Artículo / Artikulua  OpenAccess
      In some diseases it is well-known that a unimodal mortality pattern exists. A clear example in developed countries is breast cancer, where mortality increased sharply until the nineties and then decreased. This clear ...
    • Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure 

      Militino, Ana F. Upna; Ugarte Martínez, María Dolores Upna; Montesino San Martín, Manuel Upna (Springer, 2019)   Artículo / Artikulua  OpenAccess
      Outliers and missing data are commonly found in satellite imagery. These are usually caused by atmospheric or electronic failures, hampering the correct monitoring of remote-sensing data. To avoid distorted data, we propose ...
    • Improving the quality of satellite imagery based on ground-truth data from rain gauge stations 

      Militino, Ana F. Upna; Ugarte Martínez, María Dolores Upna; Pérez Goya, Unai Upna (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      Multitemporal imagery is by and large geometrically and radiometrically accurate, but the residual noise arising from removal clouds and other atmospheric and electronic effects can produce outliers that must be mitigated ...
    • On the performances of trend and change-point detection methods for remote sensing data 

      Militino, Ana F. Upna; Moradi, Mohammad Mehdi; Ugarte Martínez, María Dolores Upna (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      Detecting change-points and trends are common tasks in the analysis of remote sensing data. Over the years, many different methods have been proposed for those purposes, including (modified) Mann-Kendall and Cox-Stuart ...
    • Online relative risks/rates estimation in spatial and spatio-temporal disease mapping 

      Adin Urtasun, Aritz Upna; Goicoa Mangado, Tomás Upna; Ugarte Martínez, María Dolores Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      Background and objective: Spatial and spatio-temporal analyses of count data are crucial in epidemiology and other fields to unveil spatial and spatio-temporal patterns of incidence and/or mortality risks. However, fitting ...
    • Small area estimation of gender-based violence: rape incidence risks in Uttar Pradesh, India 

      Vicente, G.; Goicoa Mangado, Tomás Upna; Puranik, A; Ugarte Martínez, María Dolores Upna (Society of Statistics, Computer and Applications, 2018)   Artículo / Artikulua  OpenAccess
      Violence against women is considered an endemic problem in communities and countries around the world, and it has been declared an issue of epidemic proportions by the World Health Organization (WHO). In India, where the ...
    • Space-time analysis of ovarian cancer mortality rates by age groups in Spanish provinces (1989-2015) 

      Trandafir, Paula Camelia; Adin Urtasun, Aritz Upna; Ugarte Martínez, María Dolores Upna (BioMed Central, 2020)   Artículo / Artikulua  OpenAccess
      Background: Ovarian cancer is a silent and largely asymptomatic cancer, leading to late diagnosis and worse prognosis. The late-stage detection and low survival rates, makes the study of the space-time evolution of ovarian ...
    • Spatial gender-age-period-cohort analysis of pancreatic cancer mortality in Spain (1990-2013) 

      Etxeberria Andueza, Jaione Upna; Goicoa Mangado, Tomás Upna; López Abente, Gonzalo; Riebler, Andrea; Ugarte Martínez, María Dolores Upna (Public Library of Science, 2017)   Artículo / Artikulua  OpenAccess
      Recently, the interest in studying pancreatic cancer mortality has increased due to its high lethality. In this work a detailed analysis of pancreatic cancer mortality in Spanish provinces was performed using recent data. ...
    • Stochastic spatio-temporal models for analysing NDVI distribution of GIMMS NDVI3g images 

      Militino, Ana F. Upna; Ugarte Martínez, María Dolores Upna; Pérez Goya, Unai Upna (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      The normalized difference vegetation index (NDVI) is an important indicator for evaluating vegetation change, monitoring land surface fluxes or predicting crop models. Due to the great availability of images provided by ...
    • Tailoring the structural and magnetic properties of Co-Zn nanosized ferrites for hyperthermia applications
