2013 November : Biostatnet

A paper authored by young researchers of Biostatnet has been published on the October 2013 issue of the Bulletin of Statistics and Operations Research.
A paper authored by young researchers of Biostatnet entitled Young biostatisticians in Spain: career or race? has been published on the October 2013 issue of the Bulletin of Statistics and Operations Research. Altea Lorenzo-Arribas et al. discuss new opportunities and challenges for the integration of young professionals in the Biostatistics area in Spain (e.g., multidisciplinary training, collaborations with other scientists and strategic partnerships in research). This article directly relates to a roundtable celebrated in January 2013 in the framework of the 2nd General Meeting of the Network. This article intends to provide the perspective of young biostatisticians on what many experienced colleagues have been discussing for years (i.e., interdisciplinary environment, training, opportunities abroad and development of new concepts).

Seminario:"A Bayesian multivariate growth curve model"
Fecha: 22-11-2013 Autor: Emmanuel Lesaffre (Department of Biostatistics, Erasmus MC, Rotterdam, the Netherlands y I-Biostat, KU Leuven, Leuven, Belgium) Título:"A Bayesian multivariate growth curve model" Lugar: Facultad de Ciencias Económicas y Empresariales (Bilbao)   Abstract: A Bayesian multivariate growth curve model Emmanuel Lesaffre Department of Biostatistics, Erasmus MC, Rotterdam, the Netherlands I-Biostat, KU Leuven, Leuven, Belgium Most longitudinal growth curve models evaluate the evolution of each of the body characteristics separately. When applied to a `normal population' this exercise leads to univariate reference curves against which newly included individuals can be evaluated. However, normal growth should be evaluated in totality, i.e. by evaluating all body characteristics jointly. Recently, Cole et al. suggested the SITAR model which expresses individual growth curves by three subject-specific parameters indicating their deviation from a flexible overall growth curve. This model allows characterizing normal growth in a flexible though compact manner. In this paper we generalize the SITAR model in a Bayesian way to multiple dimensions. The multivariate SITAR model allows for multivariate reference regions and allows for better conditional prediction, given the past growth. The usefulness of the model is illustrated on measurements of embryonic growth taken in the first semester of pregnancy, collected in an ongoing study at Erasmus MC, Rotterdam. Further, we demonstrate how the model can be used to find determinants of early growth.
Webinar: Modelización y simulación con Mathematica. Ejemplos de aplicaciones
Fecha: 15-11-2013 a las 10:00Ponente: Guillermo Sánchez (http://diarium.usal.es/guillermo)Registro: http://www.addlink.es/eventos?task=view_event&event_id=643Contenido: En este seminario presentamos algunas de las posibilidades que ofrece Mathematica para construir simulaciones dinámicas interactivas. Empezaremos construyendo algunos ejemplos sencillos de modelización de distintos fenómenos. A continuación nos centraremos en el modelado de la distribución de sustancias (isótopos radioactivos, fármacos, tóxicos, etc.) en el cuerpo humano.
