I have a spreadsheet that calculates 1X2 prices, team goals, correct score, DNB, 1X2DC odds etc after you input the Supremacy & Total goals data.
This uses a Poisson distribution to allocate the expected number of goals.
I want to re-work the model so that if you input the 1X2 prices and the total goals it gives you the Supremacy...but am struggling to reverse the calculations.
