Cauchy distribution
From Wikipedia, the free encyclopedia
The Cauchy-Lorentz distribution (after Augustin-Louis Cauchy and Hendrik Lorentz) is a continuous probability distribution. As a probability distribution it is usually called a Cauchy distribution. Physicists know it as a Lorentz distribution.
It is used in spectroscopy to describe the spectral lines found there, and to describe resonance.[1]
The Cauchy distribution is often used in statistics as the canonical example of a "pathological" distribution. Both its mean and its variance are undefined.
