Deprivation, satisfaction and dual expressions of Gini related measures of inequality, mobility and convergence digital Deprivation, satisfaction and dual expressions of Gini related
measures of inequality, mobility and convergence
Year: 2020
This paper starts by presenting simple ways of computing the Gini index. We emphasize the dual ways of defining the Gini index and the possibility of expressing this index in terms of deprivation and satisfaction. These additional interpretations are then extended to the measurement of distributional change and convergence...

A joint decomposition of the Zenga-84 inequality index digital A joint decomposition of the Zenga-84 inequality index
Year: 2020
This paper provides a multi-decomposition (or joint decomposition) of the Zenga-84 inequality index, considering simultaneously different sources and subpopulations. The suggested procedure consists of two different stages: in the first one, each inequality pointwise measure is decomposed by sources and by subpopulations; in the second one, the decomposition of the synthetic index is obtained, by averaging the previously decomposed pointwise measures...

The joint decomposition of the Pietra index digital The joint decomposition of the Pietra index
Year: 2020
In this paper, a multi-decomposition of the Pietra index is presented. This innovative methodology allows to achieve a relevant task, since it combines simultaneously the two most celebrated kinds of decomposition: by sources and by subpopulations. The key result of the proposed procedure is the detail level of decomposition: it allows to split the value of the index, by assessing the contribution of each source in each subpopulation. It is worth noting that this final result is not reached by all the decomposition procedures, since most of them do not permit to identify the contributions at so detailed level. The proposed joint decomposition is a sort of generalization, since from it two decompositions by sources and by subpopulations of the Pietra index, already proposed in the literature, can be obtained. Beyond the methodological details, an application based on the Survey Household Income and Wealth 2018 – carried out by Bank of Italy – is provided in order to clarify the advantages of the procedure.

Decomposition by subpopulations of Gini, Bonferroni and Zenga inequality measures digital Decomposition by subpopulations of Gini, Bonferroni
and Zenga inequality measures
Year: 2020
This paper presents a common framework for the decompositions by subpopulations of Gini, Bonferroni and Zenga synthetic inequality measures. These three synthetic indexes are the weighted arithmetic means of the corresponding point measures and applying the Zenga two-step approach, decompositions based on means comparison are obtained. In the first step additive decompositions are derived for the point indexes and in the second step, using the decompositions of the point measures, we obtain the decompositions by subpopulations of the synthetic indexes...

Density-weighted quantile regression digital Density-weighted quantile regression
Year: 2020
This study proposes a new weighted quantile regression method through the introduction of weights based on a recursive estimation of the density function of residuals. The new estimators are strictly related to the quantity quantile method introduced by Radaelli and Zenga in 2006...

Intregration of survey data and big data for finite population inference in Official Statistics: statistical challenges and practical applications digital Intregration of survey data and big data for finite population
inference in Official Statistics: statistical challenges and practical
applications
Year: 2019
The Big Data expands the range of sources that have the potential to be used for Official Statistics and represents an effective reply to the declining response rates and the rising costs of conducting surveys, offering, in the meanwhile, potentially more timeliness and granular statistics...

Beyond the sampling errors: the effects of centralized data collection on total survey errors digital Beyond the sampling errors: the effects of centralized data
collection on total survey errors
Year: 2019
The main objective of this article is to show that, based on empirical experience, the introduction of a Centralized Data Collection approach (CDC), such as the one introduced in the Italian Statistical Institute from the year 2016, has a positive effect on the Total Survey Error (TSE) of current surveys. This will present the features of the new CDC approach and the innovations introduced in terms of generalized tools, services and procedural solutions applied...
