background : inequality in households’ payments on food and health expenditures presents the accessibility and utili-zation patterns between them. this study investigated the iranian rural and urban households’ inequality in payments on food and out-of-pocket health expenditures from 1998 to 2012. methods : this descriptive study was conducted through the analysis of iranian statistics centre d...

The Gini index and the Gini mean di erence of a univariate distribution are extended to measure the disparity of a general d-variate distribution. We propose and investigate two approaches, one based on the distance of the distribution from itself, the other on the volume of a convex set in (d + 1)space, named the lift zonoid of the distribution. When d = 1, this volume equals the area between ...

background: one of the important aspects of equity in health is equality in the distribution of resources in this sector. the present study aimed to assess the distribution of hospital beds in shiraz in 2014.   methods: in this retrospective cross-sectional study, the population density index and fair distribution of beds were analyzed by lorenz curve and gini coefficient, respectively. descrip...

Recent insights from the philosopher Larry Temkin have suggested a new basis for the measurement of income inequality, founded on the notion of individual complaints. about income distribution. Under certain specifications of the relationship between complaints and personal incomes it can be shown that a concept similar to the concept of deprivation then emerges. In turn deprivation is related ...

Majority voting and social evaluation functions are the main alternatives proposed in the literature for aggregatingindividual preferences. Despite these being very different, this papershows that the ranking of income distributions, symmetric under the same transformation, by S-Gini consistent social evaluation functions and majority voting coincide if and only if the inequality index under co...

This study investigates the potential of object-based texture parameters extracted from 15m spatial resolution ASTER imagery for estimating tree size diversity in a Mediterranean forested landscape in Turkey. Tree size diversity based on tree basal area was determined using the Shannon index and Gini Coefficient at the sampling plot level. Image texture parameters were calculated based on the g...

Two new normative indices of mobility are proposed. The first one is a population weighted generalized Gini mobility index and will be higher, the higher the size of the transfer between two individuals and, for a given transfer, the higher the rank difference between the individuals between whom the transfer takes place. This index is also higher, the greater the rank gap between the individua...
