6 июл. 2019 г. · The Cauchy distribution is commonly used in models in finance to represent deviations in returns from the predictive model.

12 февр. 2018 г. · Student's t-distribution becomes the Cauchy distribution when the degrees of freedom is equal to one and converges to the normal distribution.

17 мар. 2016 г. · I need to use the ratio of two variables as the dependent variable in a regression. Both variables are normally distributed but with positive values.

11 февр. 2014 г. · The ratio is Cauchy only if the denominator distribution is centered at 0. In any cases, the statistics on the ratio of y and x can be approximated as:
