# LevyDistribution

 LevyDistribution represents a Lévy distribution with location parameter and dispersion parameter .
• The probability density for value in a Lévy distribution is proportional to .  »
• The Lévy distribution LevyDistribution is a special case of the inverse gamma distribution with and . »
• LevyDistribution allows to be any real number and to be any positive real number.
