WebApr 23, 2022 · Kyle Siegrist. University of Alabama in Huntsville via Random Services. The Cauchy distribution, named of course for the ubiquitous Augustin Cauchy, is interesting for a couple of reasons. First, it is a simple family of distributions for which the expected value (and other moments) do not exist.

WebMar 15, 2024 · Cauchy distribution, in statistics, continuous distribution function with two parameters, first studied early in the 19th century by French mathematician Augustin-Louis Cauchy. It was later applied by the 19th-century Dutch physicist Hendrik Lorentz to explain forced resonance, or vibrations.

WebThe Cauchy distribution is sometimes described as pathological, because it has no mean value, no variance and no higher moments or moment generating function. Although this sounds counter-intuitive it follows from the definition of the moments (the expected value integrals for a Cauchy distribution are all infinite), and from the observation ...
