<p>Hello,</p>
<p>I have a couple of questions about data analysis on artemis<br>
</p>
I used a restraint for my fits. I've read some documentation about
it and found Matt Newville's talk
(<a class="moz-txt-link-freetext" href="https://pubweb.bnl.gov/~frenkel/BNLworkshop2001/newville.pdf">https://pubweb.bnl.gov/~frenkel/BNLworkshop2001/newville.pdf</a>). It
is reported that a restraint adds a "V" term to the chi-square
(slides number 16 and 17).
<p class="MsoNormal">According to this formula, what is the number
that artemis gives for the "restrain" parameter at the end of the
fit? How should we consider this number in the evaluation of the
fit ?</p>
<p class="MsoNormal">I also don't really know very much about the
scaling factor to apply in the formula : scale*penalty(X,a,b).
I've read that the square root of chi-square<span
style="font-size:11.0pt;line-height:115%;
font-family:"Calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:
Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-theme-font:minor-latin;
mso-bidi-font-family:"Times New
Roman";mso-bidi-theme-font:minor-bidi;
mso-ansi-language:FR;mso-fareast-language:EN-US;mso-bidi-language:AR-SA">
</span>seems to be a good size from some of Bruce Ravel's answers
in ifeffit mailing list. How does the scaling factor control the
restraint ? What is its relationship with the chi-square ?</p>
<p class="MsoNormal">Thank you in advance for your help,</p>
