We propose a generalization of the decomposition by population subgroups of the α-Gini index, the so-called multi-level subgroup decomposition. We demonstrate that all components obtained from the decomposition, can integrate in their functional form a parameter of inequality sensitivity being...

Cette 3e édition, enrichie par de nouveaux exercices et les développements les plus récents, traite de manière pédagogique les techniques - classiques et modernes - d'analyse des séries temporelles. Elle répond aux questions suivantes : Quelles sont les méthodes de prévisions de ventes...

This paper analyzes the cyclical behavior of Dow Jones by testing the existence of long memory through a new class of semiparametric ARFIMA models with HYGARCH errors (SEMIFARMA-HYGARCH); this class includes nonparametric deterministic trend, stochastic trend, short-range and long-range...

This article shows that the multidimensional Gini index is more complete than its unidimensional configuration in order to compute the contribution of each group to the overall inequality. In Languedoc-Roussillon, it indicates that the disparities are particularly generated by wage differences...
