I answered this off-list (suggesting that the OP look at the source code of the function, which is very simple). The book gives other references to the beta-binomial, including Crowder (1978), Reeve and Murdoch (1985), and Hatfield (1996), although the latter two are ecological rather than statistical examples and I doubt any of them discusses random deviate generation. ______________________________________________ R-help@r-project.org 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.
