Title: RE: About zero counts etc.
Dear all,
Jon's right - when the counts are very low - i.e. zeroes and ones around - then the correct Bayesian approach is to use Poisson statistics. This, as Jon said, has been tackled by Antoniadis et al. (Acta Cryst. (1990). A46, 692-711 Maximum-likelih
Dear Alan,Thanks for this announcement. We are of course very interested to obtain this new version, especially as we seem to be so lucky to get it for free ;-)Many thanks.Best regardsChristianOn Oct 11, 2006, at 9:56 PM, AlanCoelho wrote: Dear allVersion 4 of the Academic version of Bruker-AXS TO
Hello Joerg,

You might have a hard time convincing me on that one.

If n is zero then spending more time on the data collection might be better than
more time on the analysis.

Dear all
Version 4 of the Academic version of Bruker-AXS TOPAS, TOPAS-Academic, is now
available to degree-granting institutions comprising universities, university
run institutes, laboratories and schools. Bruker-AXS TOPAS shall be released
before the end of the year.This version is big step
Hi all,
from time to time, the problem of zero values in the pattern
is discussed. I have done an indepth Bayesian approach:
Have assumed identical probability of all values prior to
measurement and have calculated the Bayesian distribution
of probabilities after having measured n counts, its est

Please ignore my last email which was sent to the list in error. An

Hi Alan,
Would it be possible to get a license for one of my students laptops?
It's the guy who's done all the surface fitting work in the paper I sent
you recently. He's wanting to write up/finish a last bit of data
analysis from home so it would be really useful for him. I've attached
