NHL ANALYTICS METHODOLOGY
Transparency is core to our mission. Here you'll find detailed explanations of the statistical methodology that powers HockeyStats.com — including WAR (Wins Above Replacement), Expected Goals (xG), and RAPM.
WAR (Wins Above Replacement)
PublishedOur comprehensive single-number metric for evaluating NHL player value. WAR combines six components to estimate the total wins a player contributes above a replacement-level player.
Box WAR
PublishedA new HockeyStats metric that evaluates player performance in samples as small as a single game, from a few weeks of games down to one night.
Expected Goals (xG)
PublishedOur machine learning model calculates the probability that any unblocked shot becomes a goal, accounting for shot distance, angle, shot type, and pre-shot events.
RAPM (Regularized Adjusted Plus-Minus)
PublishedThe statistical technique we use to isolate individual player impact from the effects of teammates, opponents, and situational context.
Win Odds
PublishedHow we calculate pre-game win probabilities for individual NHL matchups based on team strength, home ice advantage, and other factors.
NHL Equivalency (NHLe)
PublishedHow we convert scoring rates across 100+ leagues worldwide to NHL equivalents using network analysis, enabling fair comparisons between prospects in different leagues.
