%description
Provides a function that implements the acceptance-rejection method in an
optimized manner to generate pseudo-random observations for discrete or
continuous random variables. The function is optimized to work in parallel
on Unix-based operating systems and performs well on Windows systems. The
acceptance-rejection method implemented optimizes the probability of
generating observations from the desired random variable, by simply
providing the probability function or probability density function, in the
discrete and continuous cases, respectively. Implementation is based on
