So here's some more fat in the fire! Major figures though Alan, Armel
and Bob are, I suspect their comments stems from a lack of personal
experience in the use of the correlated integrated intensity method
of refinement. We experimentalists who use the technique find that it
works very well indeed - our latest structure solution success from
the ESRF shows the two methods - Rietveld and correlated integrated
intensity methods producing the same results.
Alan,
True to your request, Alan, I will lead you through it step by step
off-line - it's not statistics but simply matrix algebra and we
experimentalists who are doing structure solution find that the two
techniques work very well in practice. And by the way, as a happy
coincidence, the combined use of Pawley and Rietveld methods gives
the sort of esds increases that Dave Cox majors on and we all know
about.
Armel,
Your problem about equipartioning applies to the data not to the
model. Again, I'll go through that off-line with you if you want.
Bob,
Again, I'll go into the details off-line as I guess that they are
beyond the interests of most of the mailing list. Suffice to say
that, in practice, the two methods give the same results.
Now I wonder which of you is going to get our J. Appl. Cryst. to
review!!!
