Asymptotic and Bootstrap Inference for the Generalized Gini Indices
The Gini index represents a special case of the generalized Gini indices, which permit to choose a level of inequality aversion and to stress the different proportions of the income distribution. In order to apply these indices to income sample data, it is necessary to use reliable inferential procedures. In fact, also if often in income studies we have large samples for which the precision of ...
متن کاملMultidimensional Generalized Gini Indices
The axioms used to characterize the generalized Gini social evaluation orderings for one-dimensional distributions are extended to the multidimensional attributes case. A social evaluation ordering is shown to have a two-stage aggregation representation if these axioms and a separability assumption are satisfied. In the first stage, the distributions of each attribute are aggregated using gener...
متن کاملA fuzzy logic approach to poverty analysis based on the Gini and Bonferroni inequality indices
Abstract: In the poverty analysis framework, a great deal of attention has been paid to the poverty measurement in terms of monetary variables, such as income or consumption. In this context, a relevant open problem is connected with the distinction between poor and nonpoor. In fact, the concept of poverty is rather vague and cannot be defined in a clear way. In this respect, following a fuzzy ...
متن کاملReliable Inference for the Gini Index
Although attention has been given to obtaining reliable standard errors for the plugin estimator of the Gini index, all standard errors suggested until now are either complicated or quite unreliable. An approximation is derived for the estimator by which it is expressed as a sum of IID random variables. This approximation allows us to develop a reliable standard error that is simple to compute....
متن کاملInference for similarity indices
Clustering methods are considered as unsupervised learning techniques as there are no predetermined subpopulations. Evaluating the results of clustering algorithms is the main topic of cluster validity. This paper tries to contribute to a better understanding and inference for the distribution, of such a case, of the Rand Index (Rand, 1971) under several conditions. Besides this, a bootstrappin...
