Webb15 mars 2024 · The Pareto distribution is a power-law probability distribution, and has only two parameters to describe the distribution: α (“alpha”) and Xm. The α value is the shape parameter of the distribution, which determines how distribution is sloped (see Figure 1).

Webbwhere x ( F) is the inverse of the cdf. The denominator is the mean of the distribution. For the Pareto distribution, the Lorenz curve is L ( F) = 1 − ( 1 − F) 1 − 1 α , from which we obtain the equation we need to solve: 0.2 = 1 − ( 1 − 0.8) 1 − 1 α.
