Dear Bruce, Thank you very much for telling me useful references! I have not fully understood yet because of my lack of knowledge of statistics, but I could roughly understand how they are estimated in Artemis. Best regards, Hiroshi. Bruce Ravel wrote:

Dear all,
Could someone tell me how the uncertainities in the fitted variables are estimated in the curve-fitting analysis in Artemis?
Thank you very much in advance for your help.
Hiroshi,
Here is one explanation from the mailing list: http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2002-October/000141.htm
Matt's followup is also very helpful: http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2002-October/000142.html
Pages 6 through 15 of the talk that I gave at the APS XAFS summer school last August are relevant to the last paragraph from the first link: http://xafs.org/Workshops/APS2008?action=AttachFile&do=get&target=Ravel_Advanced.pdf
Hope that helps, B
