This class implements methods for generating random variates from the folded normal distribution with parameters \(\mu\ge0\) and.
\[ f(x) = \phi\left(\frac{x-\mu}{\sigma}\right) + \phi\left(\frac{-x-\mu}{\sigma}\right) \qquad\mbox{for } x \ge0, \tag{fFoldedNormal} \]
where \( \phi\) denotes the density function of a standard normal distribution.
