PDL::RandVar::Histogram -- Arbitary distribution random variables
Current version is 1.0
use PDL::RandVar::Histogram $m = new PDL::RandVar::Histogram($dist);
Histogram random variables are useful for generating distributions to match arbitrary vector (N-D) data. On initialization, you feed in a clumped array whose value is proportional to the probability of landing in each bin. You get back values of indices into the original vector. If you ask for it, you can get subsampling in the mantissa of each index.
