[Jprogramming] Negative binomial random numbers

[Mike Day]

I haven't rolled my own - at least not in a long while - might have done 
in APL yonks ago!

But I see that R has a function rnegbin which is a
"Function to generate random outcomes from a Negative Binomial 
distribution, with mean|mu|and variance|mu + mu^2/theta|."

And J's addons include an R server.

So, faute de mieux,  R might serve your purpose.  Likely to be better in 
native J if you're doing lots, of course.

Ewart has probably rolled this in all sorts of ways,  so I'm copying to him.
