Well, that is an old chestnut that Cooper and Rollet used to oppose to Rietveld refinement. I think Rollet eventually agreed that Rietveld was the better method. Has Bill really gone back on that ?
Yes, see the latest issue of J. Appl. Cryst. (2004) 37, 621-628.
And there is also a book in preparation about the same old chestnut, to be edited by Springer in 2004, entitled: "Powder diffraction : the Rietveld method and the two-stage method" by G. Will.
