A new package named BiasedUrn is available.
This package implements various noncentral hypergeometric distributions,
univariate and multivariate.
Includes the distribution you get when taking colored balls from an urn
without replacement, with bias.
These distributions have many applications in models of biased sampling
and models of evolution by natural selection.
The multivariate hypergeometric distribution can be generated as a
The underlying theoretical publication is not out yet. Please see the
