Pareto distribution

Named after Vilfredo Pareto.

Pareto distribution (plural Pareto distributions)

1. (statistics) A probability distribution such that for a random variable X with that distribution holds that the probability that X is greater than some number x is given by
   ${\displaystyle \Pr(X>x)=\left({\frac {x}{x_{\mathrm {m} }}}\right)^{-k}}$
   for all x ≥ x_m, where x_m is the (necessarily positive) minimum possible value of X, and k is a positive parameter.
