论文摘要
在本文中,我们将注意力集中在一种有希望但略有低估的变异性量度 - Gini系数。我们描述了定义和解释此参数的两种新方法。使用我们的新表示,我们计算了一些概率分布的Gini索引,并更详细地描述了负二项式分布。我们还建议后者作为测量流行病学过度分散的工具。
In this paper, we draw attention to a promising yet slightly underestimated measure of variability - the Gini coefficient. We describe two new ways of defining and interpreting this parameter. Using our new representations, we compute the Gini index for a few probability distributions and describe it in more detail for the negative binomial distribution. We also suggest the latter as a tool to measure overdispersion in epidemiology.
