Comment (by chris_fonnesbeck):
I can confirm that the negative binomial does not work at all with the
first parameter <1. There should not be any rounding going on at all when
generating NB random variables.
This should probably be removed if it is not fixed, as it will not produce
valid negative binomial random numbers.
