Statistical estimation with model selection Lucien

The purpose of this paper is to explain the interest and importance of (approximate) models and model selection in Statistics. Starting from the very elementary example of histograms we present a general notion of finite dimensional model for statistical estimation and we explain what type of risk bounds can be expected from the use of one such model. We then give the performance of suitable mo...

Discipline ou spécialité: Microélectronique

Full integration of energy conversion devices for compact power supply circuits is still encountering strong technological locks, especially to integrate passive inductive and capacitive components. The increasing working frequency of those devices, which already reaches 1 Megahertz, would enable the size reduction of passive components and then their integration. Nevertheless, losses, which hi...

Functional field score: the effect of using a Goldmann V-4e isopter instead of a Goldmann III-4e isopter.

PURPOSE To investigate the underestimation of field loss in functional field score (FFS) between the Goldmann isopters III-4e and V-4e in visually impaired patients, in order to develop a predictive model for the FFS(III-4e) based on FFS(v-4e) that adjusts for possible confounders. Although the visual field is generally evaluated using Goldmann isopter III-4e, it has the disadvantage that not a...

Rhabdomyosarcome ou pseudotumeur inflammatoire

Il s’agit d’un enfant de 4 ans, sans ATCD pathologique particulier, qui présente depuis 2 mois une tuméfaction inflammatoire, douloureuse, rapidement progressive de l’œil gauche. A l’examen, l’AV était à 2/10 et on retrouve une exophtalmie, axile, inflammatoire, irréductible et non pulsatile de cet œil. Une TDM orbito-cérebrale réalisée chez ce patient montre un processus orbitaire intra et ext...
