Thanks for the numbers Holden!
So let's take our example of a moneyline odds offer of -120.
Implied probability = (- (-120) / ((- (-120)) + 100)
So let's use our example of moneyline odds offer of +180
Implied probability = 100 / (180 + 100)
I create the implied probability as a unitless measure of what the bookies odds mean in a win percentage. This is then comparable to Holden's unitless winning percentage. Too independant variables for the same event are then compared. ![]()
