Model Card
Defensive side of the points event model. Positive values mean a player's minutes tend to reduce the opponent's points per 100 possessions.
Validation here is out of sample. From two weeks into each season, a model trained on earlier games predicts each following week without learning from that week. Predictions use the players' observed minutes; each point is the minutes-weighted predicted and actual rate in that player's games. The source inputs were not verified as identical to the published model revision.
