A new approach to influence analysis in linear models
(JSTOR, 1995-10-15)
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, ...

The determination of a "least quantile of squares regression line" for all quantiles
(Elsevier Science, 1994-09-01)
Least median of squares regression has shown to be an extremely useful tool in robust regression analysis. In this note, we extend this concept to least quantile of squares regression, and propose a polynomial algorithm ...

A discretizing algorithm for location problems
(ELSEVIER SCIENCE BV, 1995)
A new and simple methodology is proposed to solve both constrained and unconstrained planar continuous single-facility location problems. As particular instances, the classical location problems with mixed gauges can be ...

Locating an undesirable facility by generalized cutting planes
(Informs, 1998-08-03)
We address the problem of locating an undesirable facility within a compact set by minimizing a strictly decreasing boundedly lower subdifferentiable function of the squared Euclidean distances to a set of fixed points. ...

Estimadores de razón: una revisión
(Universidad Politécnica de Cataluña, 1997)
En este trabajo de revision exponemos los principios básicos de la utilización de información adicional en la estimación de parámetros definidos sobre poblaciones finitas, mediante el empleo de estimadores de razón. Aunque ...

Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1993-04-01)
In this paper we address the problem of ranking a set of alternatives with partial information about the weighting coefficients. We introduce a family of quasiorders that are easily interpretable and manageable, which ...

Local influence on the general linear model
(Indian Statistical Institute, 1998)
We study the Local Influence on the General Linear Model with a perturbation scheme in the variance-covariance matrix of the random errors. The comparison of the results obtained and the conditional bias have been used to ...

Polynomial algorithms for parametric minquantile and maxcovering planar location problems with locational constraints
(Springer, 1998-12-01)
A location is sought within some convex region of the plane for the central site of some public service to a finite number of demand points. The parametric maxcovering problem consists in finding for eachR>0 the point from ...

Proceso de decisión basado en la función de esparcimiento
(Real Academia de Ciencias Exactas, Físicas y Naturales, 1999)
En este artículo, se estudia un proceso de decisión de exponencialidad basado en la función de esparcimiento para observaciones no censuradas. Existen muchos tests en la literatura estadística cuando la distribución de la ...
