"Se propone una base teórica para abordar el problema del análisis de influencia a través del concepto de sesgo condicionado, aplicándose al modelo lineal general. Así, los resultados que se obtienen pueden ser trasladados a los distintos modelos lineale

This paper analyses the possibilities of the statistical techniques in the treatment of marine ostracod populations, with the indication of the commonest problems observed in the different stages (sampling, laboratory procedures, recognition of the biocoenosis). Some additional chapters indicate the most important limitations for the...

Discriminant analysis (DA), particularly Discriminant Coordinates (DC), is broadly applied in the scientific literature and included in many statistical software packages. DC is used to analyze biomedical data, especially for differential diagnosis on the basis of laboratory profiles. Articles handling influence analysis in DA can be found in...

propose a new approach to the study of influence in the General Linear Model based on conditional bias. This approach enables us to apply such an analysis to all particular cases of this model. The theoretical foundation, on which this approach is based, does not presuppose a particular hypothesis on the distribution of the variables. Applying...

El estudio geoquímico de los sedimentos superficiales del litoral de Huelva ha permitido establecer el área marina bajo la influencia de las aguas muy contaminadas de los ríos Tinto y Odiel. Esta zona está localizada al SE de Mazagón, con concentraciones moderadas de Cu, Pb, Zn y Hg. Las muestras tomadas en el sector Isla Cristina-Punta Umbría...

The genera Oryctolagus and Lepus (order Lagomorpha) are essential elements in the trophic chain in the Iberian Peninsula, being the main prey of many predators, including some highly endangered predators such as the Iberian lynx (Lynx pardinus). Myxomatosis, a disease producing tumorations in conjunctive tissues, and produced by the Myxoma...
