Background Profile Found - Les Gini

In economics, the Gini coefficient (/ ˈ dʒ iː n i / JEE-nee), sometimes called the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income inequality or wealth inequality within a nation or any other group of people. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper Variability and Mutability. Gini-koeffisient er et statistisk mål for statistisk spredning, oppkalt etter den italienske statistikeren Corrado Gini.Vanligvis brukes koeffisienten til beregning av inntektsforskjeller eller formuesforskjeller i en befolkning. Koeffisienten angis som en tallverdi fra 0 til 1, hvor 0 indikerer at alle innbyggerne har akkurat like stor inntekt eller formue, mens tallverdien 1 indikerer at.

GINI index (World Bank estimate) - Country Ranking. Definition: Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure) among individuals or households within an economy deviates from a perfectly equal distribution The Gini Index can be used to quantify the unevenness in variable distributions, as well as income distributions among countries. The theory behind the Gini Index relies on the difference between a theoretical equality of some quantity and its actual value over the range of a related variable A Gini Index of 0.5 shows that there is equal distribution of elements across some classes. Mathematically, The Gini Index is represented by The Gini Index works on categorical variables and gives the results in terms of success or failure and hence performs only binary split In the example noted above, the Gini index would register a reading of 1, which indicates perfect inequality. If everyone had exactly the same amount of money, the index would register a reading of 0

The Gini coefficient is based on the comparison of cumulative proportions of the population against cumulative proportions of income they receive, and it ranges between 0 in the case of perfect equality and 1 in the case of perfect inequality Die Idee ist, dass bei einer reinen Entscheidung der Baum fertig ist, weshalb die Änderung des Gini-Index als Maß geeignet ist.

The Gini Index is a summary measure of income inequality. The Gini coefficient incorporates the detailed shares data into a single statistic, which summarizes the dispersion of income across the entire income distribution. The Gini coefficient ranges from 0,. Data and research on social and welfare issues including families and children, gender equality, GINI coefficient, well-being, poverty reduction, human capital and inequality., Gini coefficients, poverty rates, income, etc. Incomes are more equally distributed and fewer people are poor where social spending is high: the Nordic countries and western European countries, such as Austria, Belgium. The Gini coefficient provides an index to measure inequality, says Antonio Cabrales, a professor of economics at University College London Because this index is used in binary target variables (0,1), a gini index of 0.5 is the least pure score possible. Half is one type and half is the other. Dividing gini scores by 0.5 can help intuitively understand what the score represents. 0.5/0.5 = 1, meaning the grouping is as impure as possible (in a group with just 2 outcomes). 3 red and. The more unequal a country's income distribution, the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality the index would be zero; if income were distributed with perfect inequality, the index would be 100

(Sometimes the Gini coefficient is represented as a percentage or an index, in which case it would be equal to (A/(A+B))x100%.) As stated in the Lorenz curve article, the straight line in the diagram represents perfect equality in a society, and Lorenz curves that are further away from that diagonal line represent higher levels of inequality Gini index and entropy are the criteria for calculating information gain. Decision tree algorithms use information gain to split a node. Both gini and entropy are measures of impurity of a node.

The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line. Similar to GII, a value of 0 represents perfect equality, while an index of 100 implies perfect inequality The index is the ratio of (a) the area between a country's Lorenz curve and the 45 degree helping line to (b) the entire triangular area under the 45 degree line. The more nearly equal a country's income distribution, the closer its Lorenz curve to the 45 degree line and the lower its Gini index, e.g., a Scandinavian country with an index of 25 Value & Rank The GINI index of Afghanistan is 27.8 with a global rank of 143. Afghanistan compared to other Countries The GINI index of Afghanistan is similar to that of Austria, Kazakhstan, Montenegro, Germany, Bulgaria, Romania, Finland, Belarus, Slovak Republic, Czech Republic with a respective GINI index of 29.2, 29.0, 28.6, 28.3, 28.2,. The bias corrected Gini coefficient goes from 0 to 1. The small sample variance properties of the Gini coefficient are not known, and large sample approximations to the variance of the coefficient are poor (Mills and Zandvakili, 1997; Glasser, 1962; Dixon et al., 1987), therefore confidence intervals are calculated via bootstrap re-sampling methods (Efron and Tibshirani, 1997)
