46 p, 452.1 KB What does intrinsic mean in statistical estimation? / Garcia, Gloria (Universitat Pompeu Fabra) ; Oller, Josep M. (Universitat de Barcelona)
In this paper we review different meanings of the word intrinsic in statistical estimation, focusing our attention on the use of this word in the analysis of the properties of an estimator. We review the intrinsic versions of the bias and the mean square error and results analogous to the Cram´er-Rao inequality and Rao-Blackwell theorem. [...]

22 p, 334.6 KB Influence diagnostics in exponentiated-Weibull regression models with censored data / Ortega, Edwin M. M. ; Cancho, Vicente G. ; Bolfarine, Heleno
Diagnostic methods have been an important tool in regression analysis to detect anomalies, such as departures from the error assumptions and the presence of outliers and influential observations with the fitted models. [...]

12 p, 151.6 KB Statistical models to study subtoxic concentrations for some standard mutagens in three colon cancer cell lines / Bardina i Simorra, Xavier (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Fernandez, Laura (Universitat Autònoma de Barcelona. Departament de Genètica) ; Piñeiro, Elisabet (Universitat Autònoma de Barcelona. Departament de Genètica) ; Surrallés i Calonge, Jordi (Universitat Autònoma de Barcelona. Departament de Genètica i de Microbiologia) ; Velazquez Henar, M. Antonia (Universitat Autònoma de Barcelona. Departament de Genètica)
The aim of this work is to propose models to study the toxic effect of different concentrations of some standard mutagens in different colon cancer cell lines. We find estimates and, by means of an inverse regression problem, confidence intervals for the subtoxic concentration, that is the concentration that reduces by thirty percent the number of colonies obtained in the absence of mutagen.

The GS-distribution is a family of distributions that provide an accurate representation of any unimodal univariate continuous distribution. In this contribution we explore the utility of this family as a general model in survival analysis. [...]
