when I try to calculate the importances based on the utilities, I unfortunately don't end up with the same importances that are shown to me in the utility report. I use HB analysis.
i. Calculating the maximum range per attribute (e.g. 30 + -10)
ii. Calculating the sum of the ranges of all attributes (e.g. range attribute 1 + range attribute 2)
iii. Calculating the relative importance (e.g. importance attribute 1 = range attribute 1/ sum of ranges of all attributes)
What am I doing wrong here?
Thank you very much!
