A complete handout about the Lorenz curve including various applications, including an Excel spreadsheet graphing Lorenz curves and calculating Gini coefficients as well as coefficients of variation. LORENZ 3.0 is a Mathematica notebook which draw sample Lorenz curves and calculates Gini coefficients and Lorenz asymmetry coefficients from data ...
Derivation of the Lorenz curve and Gini coefficient for global income in 2011. Gini coefficients of income are calculated on a market income and a disposable income basis. The Gini coefficient on market income—sometimes referred to as a pre-tax Gini coefficient—is calculated on income before taxes and transfers.
Online calculator computes the Gini Coefficient, plots the Lorenz curve, and computes many other measures of concentration for any dataset Online calculator: Online (example for processing data from Table HINC-06 [ permanent dead link ] , U.S. Census Bureau, 2007: Income Distribution to $250,000 or More for Households) and downloadable ...
The Gini coefficient is a number between 0 and 1 or 100, where 0 represents perfect equality (everyone has the same income), while an index of 1 or 100 implies perfect inequality (one person has all the income and everyone else has no income).
The Lorenz curve is used to describe the inequality in the distribution of a quantity (usually income or wealth in economics, or size or reproductive output in ecology). The most common summary statistic for the Lorenz curve is the Gini coefficient, which is an overall measure of inequality within the population. The Lorenz asymmetry ...
The Gini coefficient is a measure of the deviation of the Lorenz curve from the equidistribution line which is a line connecting [0, 0] and [1, 1], which is shown in black (α = ∞) in the Lorenz plot on the right. Specifically, the Gini coefficient is twice the area between the Lorenz curve and the equidistribution line.
Gini Coefficient: A measure that represents the income or wealth distribution among a nation's residents, with 0 expressing perfect equality and 1 indicating perfect inequality. Lorenz Curve: A graphical representation of income distribution, where a perfectly straight line (45-degree line) reflects absolute equality.
The MNDif is the Gini coefficient applied to qualitative data. ... is the distance between the Lorenz curve of species distribution and the 45 degree line. It is ...
