This class implements random variate generators for the log-logistic distribution with shape parameter \(\alpha> 0\) and scale parameter.
\(\beta> 0\). The density function of this distribution is
\[ f(x) = \frac{\alpha(x / \beta)^{\alpha- 1}}{\beta[1 + (x / \beta)^{\alpha}]^2} \qquad\qquad\mbox{for } x > 0. \tag{floglogistic} \]
