We propose indices that describe the depth of consciousness (DOC) based on electroencephalograms (EEGs) acquired during anesthesia. The spectral Gini index (SpG) is a novel index utilizing the inequality in the powers of the EEG spectral components; a similar index is the binarized spectral Gini index (BSpG), which has low computational complexity. A set of EEG data from 15 subjects was obtaine...

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 article examines the application of a popular measure of sparsity, Gini Index, on network graphs. A wide variety of network graphs happen to be sparse. But the index with which sparsity is commonly measured in network graphs is edge density, reflecting the proportion of the sum of the degrees of all nodes in the graph compared to the total possible degrees in the corresponding fully connec...

348 words) Background: The assessment of population health has traditionally relied on the population’s average health measured by mortality related indicators. Researchers and policy-makers have increasingly recognized the importance of including information on health inequality and healthrelated quality of life (HRQL) in the assessment of population health. The objective of this study is to a...

In the scientific community, it is very common to try to create sound metrics for practically everything that can be measured. One of the current trends is to consider aspects from social networks for defining evaluation metrics. Following such a trend, our work proposes applying the Gini coefficient for evaluating research networks from two different perspectives. The first one analyzes the te...

We intend to point out the differences which exist between the classical Gini concentration coefficient and a proposed bipolarization index defined for an arbitrary random variable which have a finite support. In fact Gini's index measures only the "poverty degree" for the individuals from a given population taking into consideration their wages. The Gini coefficient is not so sensitive to the ...
