ShotQuality RAPM

New
Explore

Break down shooting efficiency RAPM into shot-quality, shot-making, and free-throw components on both offense and defense using a ShotQuality-based decomposition.

4-Regression Method — Runs four parallel ridge regressions (alpha = 3000) on ~650k non-turnover possessions from 2023-24 through 2025-26, with the same +1/-1 lineup matrix and 700-day time-decay weighting.

Component Attribution — Offense splits into `oSQ`, `oMake`, and `oFT`, while defense uses `dSQ`, `dContest`, and `dFT`; `oTS`/`dTS` are the totals in points per 100 shots.

Sign Convention — Positive is always good for both offense and defense (defensive signs are flipped), so higher values mean better impact on both sides.

Built as a pure lineup-adjusted model with no box-score priors (no DARKO/EPM-style stabilization) and sourced from ShotQuality pre-shot expected value data.

Includes a second-stage decomposition check (`Off TS` and `Def TS`) to validate that shot-quality, shot-making, and FT components reconstruct scoring impact.
