Calculate Player Efficiency Rating

Introduction

Understanding how to calculate the Player Efficiency Rating (PER) is crucial for basketball analysts and enthusiasts looking to gauge a player's performance relative to the time they spend on the court. PER is a complex formula developed by John Hollinger to provide a comprehensive snapshot by summarizing a player’s achievements and faults on the court. The formula takes into account various aspects such as points, assists, turnovers, and other statistics, adjusted per minute played, making it a versatile metric for evaluation.

This metric's calculation involves standardizing a player's accomplishments while considering game pace and the league's average performance. Navigating such complexities in PER calculation requires not only a solid understanding of basketball statistics but also robust tools to manage and analyze large datasets efficiently. Sourcetable addresses this need by offering an AI-powered spreadsheet assistant, making it more accessible for users to compute complex metrics like PER.

How is Player Efficiency Rating Calculated?

Overview of PER

Player Efficiency Rating (PER) is a comprehensive statistic created by John Hollinger to measure a basketball player's performance per minute based on numerous game variables. This all-in-one metric provides a detailed view of players' positive and negative on-court contributions.

Components of PER Calculation

The PER calculation involves summing up all positive aspects such as points scored, assists, rebounds, and defensive plays like steals and blocks, and subtracting negative factors which include missed shots, turnovers, and personal fouls. The formula uses a statistical point value system to adjust each action's contribution to the player's overall performance.

Understanding the PER Formula

The PER formula, expressed as uPER = (1 / MP) * [3P + (2/3) * AST + (2 - factor * (team_AST / team_FG)) * FG + (FT *0.5 * (1 + (1 - (team_AST / team_FG)) + (2/3) * (team_AST / team_FG))) - VOP * TOV - VOP * DRB% * (FGA - FG) - VOP * 0.44 * (0.44 + (0.56 * DRB%)) * (FTA - FT) + VOP * (1 - DRB%) * (TRB - ORB) + VOP * DRB% * ORB + VOP * STL + VOP * DRB% * BLK - PF * ((lg_FT / lg_PF) - 0.44 * (lg_FTA / lg_PF) * VOP)], encompasses a combination of individual statistics and team dynamics, reflecting a player’s efficiency per minute played.

Adjustments in PER

PER includes adjustments for team pace and the player's role (starters versus substitutes). These modifications ensure that PER accurately reflects a player’s performance under various game conditions and relative to team strategy.

Efficiency and Impact

By quantifying all significant basketball actions, PER asserts itself as a more exhaustive measure of a player’s impact compared to basic statistics. It not only provides a single performance metric but also harmonizes different playing environments by adjusting for game pace and roles.

This PER calculation offers an in-depth analysis, making it an essential tool for teams and analysts aiming to gauge player effectiveness accurately.

How is Player Efficiency Rating Calculated?

Player Efficiency Rating (PER), developed by John Hollinger, is a sophisticated metric used to assess a basketball player's performance per minute by balancing various statistical inputs. This comprehensive statistic integrates both accomplishments and setbacks to provide a nuanced view of a player's impact on the game.

Calculating Unadjusted PER (uPER)

The initial step in computing PER involves calculating the unadjusted PER (uPER). This is done using the formula:uPER = (1 / MP) * [ 3P + (2/3) * AST + (2 - factor * (team_AST / team_FG)) * FG + (FT *0.5 * (1 + (1 - (team_AST / team_FG)) + (2/3) * (team_AST / team_FG))) - VOP * TOV - VOP * DRB% * (FGA - FG) - VOP * 0.44 * (0.44 + (0.56 * DRB%)) * (FTA - FT) + VOP * (1 - DRB%) * (TRB - ORB) + VOP * DRB% * ORB + VOP * STL + VOP * DRB% * BLK - PF * ((lg_FT / lg_PF) - 0.44 * (lg_FTA / lg_PF) * VOP) ].

Pace and League Adjustments

Following the calculation of uPER, adjustments are made to account for variations in game pace and align with league-wide performance levels. The pace is adjusted using the formula:pace adjustment = lg_Pace / team_Pace. The final PER is then scaled such that the league average is 15, applying the formula:PER = aPER * (15 / lg_aPER).

Summarizing Player Efficiency

Through PER, every positive action like assists, rebounds, and points scored contributes positively, while negatives such as turnovers and fouls are deducted. This method allows PER to serve as a more inclusive measure of a player’s effectiveness, capturing the full spectrum of their contributions and errors throughout the season.

This sophisticated yet practical approach makes PER a valuable tool for comparing players in the NBA, offering insights that traditional statistics might overlook.

Examples of Calculating Player Efficiency Rating (PER)

Example 1: Basic Calculation

To understand how PER is calculated, consider a simplified example. If a player scores 20 points, has 5 rebounds, 3 assists, 2 steals, and 1 block in a game, but also commits 2 turnovers and misses 10 field goals and 5 free throws, their raw statistics are inputted into the PER formula. The formula adjusts these stats with a league-average factor, resulting in a PER score that reflects their performance above or below a typical player.

Example 2: Adjusting for Playing Time

Consider a player who plays only 15 minutes in a game and records 10 points, 2 rebounds, and 1 assist. Using the PER calculation, these stats are prorated to a per-minute basis and then extrapolated to the league's average playing time (usually 48 minutes). This adjustment helps compare players fairly, regardless of playing time.

Example 3: Negative Contributions

PER also accounts for negative in-game actions. For instance, if a player scores 30 points but commits 10 turnovers, the turnovers negatively impact their PER. The formula subtracts the value of turnovers and other negative stats from the positive contributions to ensure the score accurately reflects overall player efficiency.

Example 4: Comparison Across Different Games

To demonstrate how PER can vary, consider a player who scores 25 points with 5 rebounds in one game, and then 10 points with 10 rebounds in another. Using the PER formula, each game's statistics are adjusted for pace and efficiency, providing a comparative view of the player's performance in different contexts.
