Con questo numero la rivista Statistica & Applicazioni conclude il primo triennio di vita. L’esperienza acquisita, i nuovi orientamenti della ricerca scientifica ed i criteri di valutazione della stessa, ci stimolano ad apportare alcuni cambiamenti significativi già nel prossimo numero.
On the Decomposition of the Gini’s
Mean Difference and Concentration Ratio
digital
Year:
2005
In this paper we propose a decomposition for the Gini’s mean difference of a real variate obtained as the sum of c variates observed on a finite population.
On the completeness of the family
of factorizable densities
digital
Year:
2006
The family of continuous distribution laws which factorize in two positive functions, one depending on the variable only and the other one depending on a scalar parameter exclusively, is concerned.
A new index to measure association between cat-egorical and ordinal variables
digital
Year:
2005
In this paper a new index to analyse the dependence between categorical variables is presented and is compared to other measures of association, mainly based on the X2 Pearson’s statistic.
Capitale sociale e processi produttivi locali: un’analisi a livello provinciale

Extensions of Dagum’s Gini decomposition
digital
Year:
2006
The purpose of this paper is to extend Dagum’s Gini decomposition (“A New Approach to the Decomposition of the Gini Income Inequality Ratio”, Empirical Economics 22(4), 515-531, 1997a) following three types of theoretical modelisations.
A few remarks on the estimation of some
variability measures
digital
Year:
2006
This paper intends to highlight a few considerations on the choice of a variability measure and its estimate, focusing on the standard deviation, the mean deviation and the mean difference.
In search of an international standard of
inequality measurement
digital
Year:
2006
This paper compares the Gini and Euclidian norms (and their related families) using three dimensional representations.
Towards understanding the Lorenz curve using the Ordered uniform spacings
digital
Year:
2006
This paper investigates the Ordered uniform spacings and produces the associated moment generating function of the Gini coefficient of inequality.
