%description
Implements multinomial sampling using the conditional binomial method (the
same algorithm as used in the GSL). Benchmarking shows it to be faster than
the Alias method implemented in
Statistics::Sampler::Multinomial::AliasMethod, presumably because the calls
to the PRNG are inside XS and avoid perl subroutine overheads (and
profiling showed the RNG calls to be the main bottleneck for the Alias
method).

There is a subclass that uses a hierarchical index for the draw() method in
Statistics::Sampler::Multinomial::Indexed.

For more details and background about the various approaches, see
