I have the following problem
I have 3 options with different ranks:
I would like to normalize them to 0..1 scale.
The problem is that actually the value 0 is "better" than value 3, so I would reverse the values beforehand and use 1/A, 1/B and 1/C instead.
So the normalized weigh for A on the 0..1 scale would be:
However if A, B or C are zeros there can not be any reverse value. How to normalize in this case?
