%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. Proposed by von Neumann J. (1951),
<https://mcnp.lanl.gov/pdf_files/>, 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 references CASELLA, George at al. (2004)
<https://www.jstor.org/stable/4356322>, NEAL, Radford M. (2003)
<https://www.jstor.org/stable/3448413> and Bishop, Christopher M. (2006,
ISBN: 978-0387310732).
