simple questions about R (fwd)
...ieved another piece of mail.....about the RNG in Splus 4.0 or later indicating it was modified and getting worse. I only have Splus 3.4 for HP. So I cannot try it. This makes the idea of using the pre-generated RN on CDROM more appealing..

R and Ox
...ssible problem lies in the fact that, although free for academic use, Ox is not open source. I too have been using Ox for computer-intensive programming. I also code some of my programs in C, but I always try Ox first, and in most cases it is efficient enough. For details, see http://www.de.ufpe.br/~cribari/ox.pdf and also Cribari-Neto, F. (1997).

inverse.gaussian, nbinom
Two questions: 1. inverse.gaussian is up there as one of the glm families, but do people ever use it? There is no inverse.gaussian in the R distribution family, and when I checked McCullagh & Nelder, it only appeared twice in the book (according to subject index), once in the table on p. 30 and once on p. 38 in a passing sentence. Is there a good reference on this distribution? 2. When I
