Detailed Description

This class implements random variate generators for the hyperbolic secant distribution with location parameter \(\mu\) and scale parameter \(\sigma\).

The density function of this distribution is

\[ f(x) = \frac{1}{2 \sigma} \mbox{ sech}\left(\frac{\pi}{2} \frac{(x - \mu)}{\sigma}\right), \qquad-\infty<x < \infty. \tag{fHyperbolicSecant} \]
