The Cauchy distribution, named after Augustin Cauchy, is a continuous probability distribution. It is also known, especially among physicists, as the Lorentz distribution (after Hendrik Lorentz), Cauchy–Lorentz distribution, Lorentz(ian) function, or Breit–Wigner distribution. The Cauchy distribution See more A function with the form of the density function of the Cauchy distribution was studied geometrically by Fermat in 1659, and later was known as the witch of Agnesi, after Agnesi included it as an example in her 1748 calculus … See more The Kullback-Leibler divergence between two Cauchy distributions has the following symmetric closed-form formula: Any See more Mean If a probability distribution has a density function $${\displaystyle f(x)}$$, then the mean, if it exists, is … See more Let $${\displaystyle u}$$ be a sample from a uniform distribution from $${\displaystyle [0,1]}$$, then we can generate a sample, $${\displaystyle x}$$ from … See more Probability density function The Cauchy distribution has the probability density function (PDF) See more The Cauchy distribution is an example of a distribution which has no mean, variance or higher moments defined. Its mode and median are … See more Because the parameters of the Cauchy distribution do not correspond to a mean and variance, attempting to estimate the parameters of the Cauchy distribution by using a sample mean and a sample variance will not succeed. For example, if an i.i.d. sample of … See more WebSep 5, 2010 · For example, those that have a scale parameter, such as cauchy-dist, logistic-dist, exponential-dist and normal-dist, are typically undefined for a zero scale.However, in floating-point math, it is often useful to simulate limits in finite time using special values like +inf.0.Therefore, when a scale-parameterized family’s constructor …
