The family of Pareto distributions is parametrized by a pair of positive numbers ( x 0, α). If X is a random variable with this distribution, then we have Pr ( X > x) = ( x 0 x) α for x ≥ x 0. Let Y = log e ( X / x 0). Then for y ≥ 0 we have

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. Hence 1 − 1 α = log ( 0.8) / log ( 0.2) α = 1 1 − log ( 0.8) / log ( 0.2) = 1.160964 …
