WebbThe basic Pareto distribution with shape parameter a ∈ ( 0, ∞) is a continuous distribution on [ 1, ∞) with distribution function G given by G ( z) = 1 − 1 z a, z ∈ [ 1, ∞) The special case a = 1 gives the standard Pareto distribution. The Pareto distribution is named for the economist Vilfredo Pareto.
