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 special case. The underlying theoretical publication is not out yet. Please see the package vignette and www.agner.org/random/theory/ if you need the theory details. _______________________________________________ R-packages mailing list R-packages@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-packages ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
