THE SCORIGAMI PROJECTOR
The tool below allows you to explore the pre-game and in-running probability of a scorigami. For those who may not be familiar with the term, a scorigami is a score that has never been seen before.
Because it calculates scorigami probabilities by simulating the remainder of the game, it can also provide in-running estimates for the probability of a home team win or a home team draw.
The default SDs and correlation between home and away scores are reasonable for most games, although there is some evidence of heteroskedasticity in margins and totals as their expected values grow in absolute terms.
Let me know if you have any feature requests (no promises).
