In probability theory and statistics, the Lévy distribution, named after Paul Lévy, is a continuous probability distribution for a non-negative random variable. In spectroscopy, this distribution, with frequency as the dependent variable, is known as a van der Waals profile. It is a special case of the inverse-gamma … See more The probability density function of the Lévy distribution over the domain $${\displaystyle x\geq \mu }$$ is where $${\displaystyle \mu }$$ is the location parameter See more Random samples from the Lévy distribution can be generated using inverse transform sampling.
