around the time of the Great Recession, in 2008,scholars Branko Milanovic and Christoph Lakner surmisethat the global Gini coefficient for income was 0.705. This is a moderate decrease from 1988’s estimated coefficient of 0.722, meaning that, by this measure, global inequality has slightly decrea...

The number “1” signifies a higher level of disorder or more impurity. Although there can be other numbers of groups or classes present in the dataset that can be greater than 1. In the case of machine learning (and decision trees), 1 signifies the same meaning, that is, the higher ...

The Gini ratio (or coefficient), which measures income distribution inequality, is an important indicator to assess the degree of 'righteousness' in a country (although this indicator does have its flaws). A Gini coefficient of 0 indicates perfect equality, while a coefficient of 1 indicates perf...
Economists have devised several ways of making such comparisons with a single index number. The most popular of these is the Gini index (or coefficient or ratio or number). While it simplifies com parisons, however, the Gini is not easy to explain. Here's an attempt to do so. ...
Gini coefficientinequality decompositionGini residualIn this paper we reconsider the Dagum decomposition of the Gini index and we compare this decomposition with the decompositions proposed by Mookherjee and Shorrocks and by Lambert and Aronson. In so doing, a deeper insight into the meaning of the ...

The standard deviation of 𝜖ϵ is selected such that the correlation coefficient between Y and X takes the values 𝜌={0.5,0.95}ρ={0.5,0.95}, meaning cases of both weak and strong correlations are analysed. Applying this method, an additional auxiliary variable Z is also generated, and...
