Hyperbolic secant distribution

I hadn’t run into the hyperbolic secant distribution until I saw a paper by Peng Ding [1] recently. If C is a standard Cauchy random variable, then (2/π) log |C| has a hyperbolic secant distribution. Three applications of this distribution are given in [1]. Ding’s paper contains a plot comparing the density functions for the hyperbolic […] The post Hyperbolic secant distribution first appeared on John D. Cook....
