Age- and sex-specific spatio-temporal patterns of colorectal cancer mortality in Spain (1975-2008)
In this paper, space-time patterns of colorectal cancer (CRC) mortality risks are studied by sex and age group (50-69, ≥70) in Spanish provinces during the period 1975-2008. Space-time conditional autoregressive models are ... -
Alleviating confounding in spatio-temporal areal models with an application on crimes against women in India
Assessing associations between a response of interest and a set of covariates in spatial areal models is the leitmotiv of ecological regression. However, the presence of spatially correlated random effects can mask or even ... -
Bayesian inference in multivariate spatio-temporal areal models using INLA: analysis of gender-based violence in small areas
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 ... -
Bayesian modeling approach in Big Data contexts: an application in spatial epidemiology
In this work we propose a novel scalable Bayesian modeling approach to smooth mortality risks borrowing information from neighbouring regions in high-dimensional spatial disease mapping contexts. The method is based on the ... -
Big problems in spatio-temporal disease mapping: methods and software
Background and objective: Fitting spatio-temporal models for areal data is crucial in many fields such as cancer epidemiology. However, when data sets are very large, many issues arise. The main objective of this paper is ... -
Body composition and resting energy expenditure in a group of children with achondroplasia
Background: Persons with achondroplasia develop early obesity, which is a comorbidity associated with other complications. Currently, there are no validated specific predictive equations to estimate resting energy expenditure ... -
Búsqueda de submercados inmobiliarios mediante modelos de mixturas
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2003) Contribución a congreso / Biltzarrerako ekarpenaLa heterogeneidad presente en el mercado inmobiliario dificulta enormemente su análisis y puede conllevar la presencia de submercados. En este caso, el modelo clásico de regresión lineal múltiple, ampliamente utilizado ... -
Checking unimodality using isotonic regression: an application to breast cancer mortality rates
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 ... -
Crime against women in India: unveiling spatial patterns and temporal trends of dowry deaths in the districts of Uttar Pradesh
Crimes against women in India have been continuously increasing lately as reported by the National Crime Records Bureau. Gender-based violence has become a serious issue to such an extent that it has been catalogued as a ... -
Cytokinins are involved in drought tolerance of Pinus radiata plants originating from embryonal masses induced at high temperatures
Vegetative propagation through somatic embryogenesis is an effective method to produce elite varieties and can be applied as a tool to study the response of plants to different stresses. Several studies show that environmental ... -
Detecting change-points in the time series of surfaces occupied by pre-defined NDVI categories in continental Spain from 1981 to 2015
The free access to satellite images since more than 40 years ago has provoked a rapid increase of multitemporal derived information of remote sensing data that should be summarized and analyzed for future inferences. ... -
The effect of changing temperature and agar concentration at proliferation stage in the final success of Aleppo pine somatic embryogenesis
(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2017) Artículo / ArtikuluaAim of the study: The effect of physical and chemical conditions at proliferation stage was evaluated in order to elucidate if this stage is the determinant phase to induce a marked effect in Pinus halepensis somatic ... -
Effect of thermal stress on tissue ultrastructure and metabolite profiles during initiation of Radiata pine somatic embryogenesis
Climate change will inevitably lead to environmental variations, thus plant drought tolerance will be a determinant factor in the success of plantations and natural forestry recovery. Some metabolites, such as soluble ... -
La estadística en la investigación en ciencias de la salud
Statistics and health research are closely related. Statistical methods and analysis are essential components in any research field and have acquired a relevant role in recent decades. In this context, the Universidad ... -
Estimación del desempleo por comarcas en Navarra
(Gobierno de Navarra, Departamento de Economía y Hacienda, 2005) Contribución a congreso / Biltzarrerako ekarpenaEl conocimiento del desempleo en una región es un indicador potente del ritmo de crecimiento de una economía, ya que de forma indirecta mide su capacidad para generar empleo. El Instituto de Estadística de Navarra está ... -
Estimating LOCP cancer mortality rates in small domains in Spain using its relationship with lung cancer
The distribution of lip, oral cavity, and pharynx (LOCP) cancer mortality rates in small domains (defined as the combination of province, age group, and gender) remains unknown in Spain. As many of the LOCP risk factors ... -
Estimating unemployment in very small areas
In the last few years, European countries have shown a deep interest in applying small area techniques to produce reliable estimates at county level. However, the specificity of every European country and the heterogeneity ... -
Evaluating recent methods to overcome spatial confounding
The concept of spatial confounding is closely connected to spatial regression, although no general definition has been established. A generally accepted idea of spatial confounding in spatial regression models is the change ... -
Exploring disease mapping models in big data contexts: some new proposals
La representación cartográfica de enfermedades es un área de investigación muy relevante y significativa dentro del campo de la estadística espacial (datos de área), ya que ofrece un apoyo muy importante para la toma de ... -
Filling missing data and smoothing altered data in satellite imagery with a spatial functional procedure
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 ...
