This study explored the association between income inequality and use of dental services and the role that investment in health care plays in explaining that association. We pooled individual-level data from 223,299 adults, 18 years or older, in 66 countries, who participated in the World Health Organization (WHO) World Health Surveys with country-level data from different international sources...

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....

This paper discusses the comparison between two kinds of features in clustering of some literary poems by the same author, the Romanian poet, Mihai Eminescu. Using Precision, Recall, Rand Index, Relative Precision and Purity measures we conclude that the topics of poems are better characterized by the phonemes as features than by geometric properties (described by six indicators: V/N ;A; Λ;V ar...

The aim of this paper is to present an axiomatization of a generalization of Shannon’s entropy starting from partitions of finite sets. The proposed axiomatization yields as special cases the Havrda-Charvat entropy, and thus, provides axiomatizations for the Shannon entropy, the Gini index, and for other types of entropy used in classification and data mining. Keywords—Shannon entropy, Gini ind...

where x and y are positive variables and r and s are real variables. They are also called sum mean values. There has been a lot of literature such as [3, 4, 5, 6, 9, 10, 11, 12, 13, 19, 20, 21] and the related references therein about inequalities and properties of Gini means. The aim of this paper is to prove the monotonicity and logarithmic convexity of Gini means G(r, s;x, y) and related fun...
