The Feller–Pareto distribution generalizes Pareto Type IV. Pareto types I–IV. The Pareto distribution hierarchy is summarized in the next table comparing the survival functions (complementary CDF). When μ = 0, the Pareto distribution Type II is also known as the Lomax distribution.

Web15 Nov 2024 · We noted that for ρ = 1, our model reduces to the ordinary power law (the Pareto-type 1 distribution) and that a δ-truncated Pareto-type 2 distribution yields ρ → 1 … Web1 Sep 2016 · A new Pareto-type distribution is introduced and studied. This new model is a generalization of the well-known Pareto distribution. We derive some of its probabilistic and inferential properties.We deduce the mathematical form of the Lorenz curve and the Gini index associated with the new model.
