The Bradford distribution and the Gini index

  • Q. L. Burrell


It is pointed out that the so-called “Bradford distribution” derived by Leimkuhler is more properly viewed as the theoretical form of a variant of the Lorenz curve. The equation of this Leimkuhler curve allows an easy calculation of the Gini coefficient of concentration which can be compared with empirical values.
