Lorenz method
WebThe Lorenz curve displays the deviations of the empirical distribution from a perfectly equal distribution as the difference between two graphs (the distribution curve and a diagonal line of perfect equality). This function calculates G G and plots the Lorenz curve optionally. Web9 de abr. de 2009 · Lorenz System of Equations These three linked equations were written by Edward Lorenz who at the time was studying weather patterns. There are six variables for this equation. There is of course x, y and z but there is also , and . Before graphing this set of equations values must be assigned for , and .
