BACKGROUND The assessment of population health has traditionally relied on the population's average health measured by mortality related indicators. Researchers have increasingly recognized the importance of including information on health inequality and health-related quality of life (HRQL) in the assessment of population health. The objective of this study is to assess the health of Americans...
Socioeconomic status has a robust positive relationship with several health outcomes at the individual and population levels, but in the case of HIV prevalence, income inequality may be a better predictor than absolute level of income. Most studies showing a relationship between income inequality and HIV have used entire countries as the unit of analysis. In this study, we examine the associati...
In this article we give theoretical results for different stochastic orders of a log-scale-location family which uses Tsallis statistics functions. These describe the inequalities moments or Gini index according to parameters. We also compute mean in case q-Weibull and q-Gaussian distributions. The paper is aimed at analyzing order between survival functions, Lorenz curves (as consequences) tog...
Credit scoring models are widely used to predict the probability of client default. To measure the quality of such scoring models it is possible to use quantitative indices such as the Gini index, Kolmogorov-Smirnov statistics (KS), Lift, the Mahalanobis distance, and information statistics. This paper reviews and illustrates the use of these indices in practice.
