Disliked{quote} Can you provide me with a reference & page from VBPT that provides an example how & why the SF is used in analysis? TPO_AB>TPO_BL , TPO_BL>TPO_AB ,TPO_AB/TPO_BL....... none = SF They are TPO measures of imbalance , and have nothing to do with the "quality" of the shape of the profile. It seems you missed TPO analysis in both MOM and VBPT.Ignored
I've already explained to ruma that they are two totally different SF calculation, as already said SF_jonesandciscowebsite and SF_frombandungindicator are not comparable.
The first "measure" the quality of bell distribution, the last "measure" imbalance, SF_frombandungindicator = TPO_AB/TPO_BL.
