The spatial scan statistic is an important tool for spatial cluster detection. There have been numerous studies on scanning window shapes. However, little research has been done on the maximum scanning window size or maximum reported cluster size. Recently, Han et al. proposed to use the Gini coefficient to optimize the maximum reported cluster size. However, the method has been developed and e...

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....

Spatial scan statistics with circular or elliptic scanning windows are commonly used for cluster detection in various applications, such as the identification of geographical disease clusters from epidemiological data. It has been pointed out that the method may have difficulty in correctly identifying non-compact, arbitrarily shaped clusters. In this paper, we evaluated the Gini coefficient fo...

background and purpose: utilization of health care services and food influence the health status. the food and health care expenditure ratios determine the importance level of them in household's consumption expenditures. we aimed to investigate the iranian rural and urban food and health expenditure ratios inequality during 1998 to 2012. materials and methods: this is a descriptive longit...

We have analyzed the determinants of the Gini coefficient for income and expenditure. In both cases, we do not find support for the Kuznets inverted-U hypothesis. From economic globalization viewpoint, the opening of goods markets reduces income inequality both in the short run (the Gini coefficient for income) and in the long run (the Gini coefficient for expenditure). On the other hand, the o...

Gini index is a widely used measure of economic inequality. This article develops a theory and methodology for constructing a confidence interval for Gini index with a specified confidence coefficient and a specified width without assuming any specific distribution of the data. Fixed sample size methods cannot simultaneously achieve both specified confidence coefficient and fixed width. We deve...
