Lets assume that team A and team B will play a match, and their powers are calculated like this:
A: 20
B: 10
From this; we conclude that A has a winning probability of 66.6%, and B has a winning probability of 33.3%.
Now let's assume that, using a model powers of team A and B are calculated like this:
A: 8.36
B: -7.15
How can the winning probabilities of team A and team B can be calculated ?
Please don't tell me to add +8 to both team's powers because it gives ridicilous probabilities. There should be a statistical way to find probability IMO. Does anyone know ?
Thanks in advance.
