Vantage uses a unique weighting for each matchup based on four components:
Player Only: stats from only the subject player against the selected opponent
Nearest Neighbors: stats from the 5 most similar players to the subject using a nearest neighbors approach
Positional Group: stats from the subject player’s position against the selected opponent
Recent Opponent Games: stats from all players against the selected opponent in its most recent 5 games.
Vantage’s default weighting adjusts depending on how many chances the subject player has had against the selected opponent team for the Player Only component. The remainder of each matchup rating is split 50-25-25 among Nearest Neighbors, Positional Group, and Recent Opponent Games.
Customized Weighting gives you the option to use your secret sauce and change the unique default weightings for the four components to whatever you want. Watch how the matchup ratings change based on how much weight you give to any individual component.
