Generate random numbers from a Cauchy distribution The Cauchy distribution has a single parameter, ɗ. The standard Cauchy distribution is symmetrical. In some literature reference is made to a positive Cauchy distribution, and the lp.coshy object can optionally produce this variant. Although not found in the literature, lp.coshy supports a negative variant for the sake of symmetry to the positive form. Although the standard Cauchy distribution is symmetrical around zero, its mean does not converge but is undefined. Sooner of later one gets used to this.
