scipy.stats.levy_stable = <scipy.stats._continuous_distns.levy_stable_gen object>[source]

A Levy-stable continuous random variable.

As an instance of the rv_continuous class, levy_stable object inherits from it a collection of generic methods (see below for the full list), and completes them with details specific for this particular distribution.
