I vote that Karl and Jim both deserve thanks for raising and
discussing this topic.

It is perhaps worth noting that there are other widely used
statistics that produce "impossible" values. The Bonferroni
test, for example, can produce ps > 1 if one computes LSD p x
# comparisons (as reported in SPSS, for example). SPSS rounds
these to 1. Perhaps similar convention is adopted for rb?
I'm hard-pressed to decide whether to thank Karl for raising
this interesting question, or berate him for taking me away
from my marking to do this exercise! Or perhaps the latter
should be a thanks as well?
Take care Jim
