Hi Folks,
There has been past correspondence regarding Catherine Loader's
Bell Labs (oops, Lucent) paper

  "Fast and Accurate Computation of Binomial Probabilities"

which gives the algorithm on which R's dbinom() is based.

The original URL given in the R documentation "?dbinom" is:

http://cm.bell-labs.com/cm/ms/departments/sia/catherine/dbinom

but this link is dead. Likewise, Marc Schwarz (in reply to
Aries Arditi on Thu Dec 11 2003) gives

  http://kiefer.stat.cwru.edu/~catherine/pubs.html

  "There is a link to the paper (as a Postscript file)
   at the bottom of that page, however the link appears
   to be dead."

I've just discovered that Catherine Loader seems to have cunningly
encoded herself as "c at herine.net". So now we can find a URL
for her dbinom:

  http://www.herine.net/stat/software/dbinom.html

which points to a PDF of the above paper at

  http://www.herine.net/stat/papers/dbinom.pdf

(which, today at least, works). More generally, see

  http://www.herine.net/stat/index.html

Best wishes to all,
Ted.
