1991–92 NBA Season
Regularized Adjusted Plus/Minus
RAPM isolates each player’s per-100-possession impact on both ends of the floor by regressing all simultaneous lineup combinations against observed point differentials.
The 95% credible interval (Low / High) reflects estimation uncertainty — players with fewer possessions have wider intervals.
Positive = better than average per 100 possessions.

Using the 249-game sample, team win totals were projected three ways:
MLE (maximum likelihood — raw sample rates scaled to 82 games),
Bayes (Bayesian estimator with a 0.500 prior — shrinks extreme small-sample records toward league average),
and compared against ground truth (actual full-season records).
The Bayes estimator substantially outperforms MLE, particularly for teams with few games sampled.

Squared Statistics
This analysis draws on the Historical RAPM Project — the only possession-level lineup database for the pre-play-by-play NBA era, reconstructed game by game from video since 2021.
