A Bayesian stochastic SIRS model with a vaccination strategy for the analysis of respiratory syncytial virus

Jornet-Sanz, Marc; Corberán-Vallet, Ana; Santonja, F.; Villanueva Micó, Rafael Jacinto (Institut d'Estadística de Catalunya (Idescat), 2017-06)

[EN] Our objective in this paper is to model the dynamics of respiratory syncytial virus in the region of Valencia (Spain) and analyse the effect of vaccination strategies from a health-economic point of view. Compartmental ...
A mesoscale analysis of relations between fish species richness and environmental and anthropogenic pressures in the Mediterranean Sea

Carmezim, Joao; Pennino, Maria Grazia; Martínez-Minaya, Joaquín; Conesa, David; Coll, Marta (Elsevier, 2022-09)

[EN] Although there is a great knowledge about individual anthropogenic threats to different fish species in the Mediterranean Sea, little is known about how these threats accumulate and interact to affect fish species ...
A study of heterogeneity of environmental variance for slaughter weight in pigs

Ibañez Escriche, Noelia; Varona, L.; Sorensen, D.; Noguera, J.L. (Cambridge University Press, 2008)

[EN] This work presents an analysis of heterogeneity of environmental variance for slaughter weight (175 days) in pigs. This heterogeneity is associated with systematic and additive genetic effects. The model also postulates ...
An application of change-point recursive models to the relationship between litter size and number of stillborns in pigs

Ibáñez-Escriche, Noelia; López de Maturana, E.; Noguera, J. L.; Varona, L. (American Society of Animal Science, 2010-11)

[EN] We developed and implemented change-point recursive models and compared them with a linear recursive model and a standard mixed model (SMM), in the scope of the relationship between litter size (LS) and number of ...
Bayesian threshold analysis of direct and maternal genetic parameters for piglet mortality at farrowing in Large White, Landrace, and Pietrain populations

Ibáñez-Escriche, Noelia; Varona, L.; Casellas, J.; Quintanilla, R.; Noguera, J. L. (American Society of Animal Science, 2009-01)

[EN] A Bayesian threshold model was fitted to analyze the genetic parameters for farrowing mortality at the piglet level in Large White, Landrace, and Pietrain populations. Field data were collected between 1999 and 2006. ...
Canalisation analysis of birth weight in Bruna dels Pirineus beef cattle

Fina, M.; Ibáñez-Escriche, Noelia; Piedrafita, J.; Casellas, J. (American Society of Animal Science, 2013-07)

[EN] Although heteroskedasticity has been a main topic of interest in beef cattle during recent decades, the current availability of canalization models provided new insights for animal breeding programs. Within this ...
Genetic evaluation combining purebred and crossbred data in a pig breeding scheme

Ibáñez-Escriche, Noelia; Reixach, J.; Lleonart, N.; Noguera, J. L. (American Society of Animal Science, 2011-12)

[EN] Genetic evaluations using purebred data alone and combined purebred and crossbred information were performed for lean meat percentage in a pig breeding scheme. One purebred (PB) model and 2 crossbred models (CCPS1 and ...
GSEVM v.2: MCMC software to analyze genetically structured environmental variance models

Ibáñez-Escriche, Noelia; Garcia, M.; Sorensen, D. (Blackwell Publishing, 2010-06)

[EN] This note provides a description of software that allows to fit Bayesian genetically structured variance models using Markov chain Monte Carlo (MCMC). The gsevm v.2 program was written in Fortran 90. The DOS and Unix ...
Individual efficiency for the use of feed resources in rabbits

Piles, Miriam; García-Tomas, M.; Rafel, O.; Ibañez Escriche, Noelia; Ramon, J.; Varona, L. (American Society of Animal Science, 2007-11)

[EN] A Bayesian procedure, which allows consideration of the individual variation in the feed resource allocation pattern, is described and implemented in 2 sire lines of rabbit (Caldes and R). The procedure is based on a ...
La significación es irrelevante y los P-valores engañosos. Qué hacer

Blasco Mateu, Agustín (Asociación Interprofesional para el Desarrollo Agrario, 2011)

[EN] The main statistical methods used in agricultural research for treatment comparison and for describing uncertainty about estimated parameters are reviewed. Since wrong interpretations of these methods are common, ...
New insights for enhancing feed efficiency

Mora Fenoll, Mónica (Universitat Politècnica de València, 2025-09-27)

[ES] La tesis abarca una serie de estudios destinados a mejorar los programas de selección genética para aumentar la eficiencia alimentaria en dos etapas de la vida productiva de los cerdos: lactación y crecimiento. En los ...
RESPONSE TO SELECTION FOR GROWTH RATE IN RABBITS ESTIMATED BY USING A CONTROL CRYOPRESERVED POPULATION

Piles, M.; Blasco, A. (World Rabbit Science. ICTA. UPV, 2003)

[EN] An experiment of selection for growth rate in rabbits was carried out. Response to selection was estimated by analyzing a mixed model and estimating the genetic effects of the animals in each generation, and also by ...
