APBRmetrics takes its name from the acronym APBR, which stands for the Association for Professional Basketball Research.

A book which is written by Dean Oliver. In his book , Oliver highlights general strategies for teams when they're winning or losing and what aspects should be the focus in either situation. He describes and quantifies the jobs of team leaders and role players, then discusses the interactions between players and how to achieve the best fit.

Oliver conceptualizes the meaning of teamwork and how to quantify the value of different types of players working together. He examines historically successful NBA teams and identifies what made them so successful: individual talent, a system of putting players together, or good coaching.

A Bayesian network is a probabilistic graphical model that represents a set of variables and their probabilistic independencies.

Bayesian Networks are used in predicting the outcome of sports events

George William “Bill” James is a baseball writer, historian, and statistician whose work has been widely influential. Since 1977, James has written more than two dozen books devoted to baseball history and statistics. His approach, which he termed sabermetrics in reference to the Society for American Baseball Research (SABR), scientifically analyzes and studies baseball, often through the use of statistical data, in an attempt to determine why teams win and lose. In 2006, Time named him in the Time 100 as one of the most influential people in the world.

In an essay published in the 1984 Abstract, James vented his frustration about Major League Baseball's refusal to publish play-by-play data of every game. James proposed the creation of Project Scoresheet, a network of fans that would work together to collect and distribute this information.
 

A metric that reflects team-specific variation in winning percentage over time and league-specific variation. Based on estimation of a model of the determination of annual attendance in professional baseball during the past 100 years, variation in the CBR explains more of the observed variation in attendance than other alternatives measures of competitive balance, suggesting that CBR is a useful metric.

A unique way of illustrating a revealing summary of a basketball game with a chart showing the point innovative plots which has been presented by Peter H. Westfall in 1990.

The Herfindahl index, also known as Herfindahl-Hirschman Index or HHI, is a measure of the size of firms in relationship to the industry and an indicator of the amount of competition among them.

The Herfindahl Index can be used to measure scoring balances for NBA teams.

To calculate HHI for each team: (1) divide each player's points scored by the total number of points scored by the team, (2) square that result for each player, (3) sum those squares.

The home-court advantage is the net effect of several factors that may have an (generally positive) effect on the play of the home team and an (generally negative) effect on the play of the road team.

Possible Sources of Home Court Advantage in Basketball:

• Psychological support of the fans.

• Comfort of being at home, rather than traveling.

• Referees give home teams the benefit of the doubt?

• Teams are familiar with particulars/eccentricities of their home court.

• Different distributions of rest between home and road teams
  

Calculating The Home Court Advantage:
Subtracting one team’s power rating from another can help predicting point diffential between the two teams. Unless the game is being played at a neutral site the "home court advantage" factor needs to be incorporated for more accurately predicting the point differential of a game.

Knowing the distribution of the teams' home and road performances provides predictive information on estimating home court advantage. The probability of a "random point is picked in the home team's point distribution being greater than the random point picked in road team's point distribution" gives an estimate of the home court advantage.

LRMC (Logistic Regression Markov Chain) is a college basketball rankings system designed to use only basic scoreboard data, including which teams played, which team had home court advantage and the margin of victory.

It was originally designed by Joel Sokol and Paul Kvam and has been maintained and improved by Sokol and George Nemhauser, all three optimization and statistics professors in the Stewart School of Industrial and Systems Engineering at Georgia Tech.

A research-driven approach that relies heavily on empirical analysis of player performance.

Oakland Athletics' general manager Billy Beane built successful baseball teams year after year, rather than relying on the gut instincts of old-time scouts, as was standard practice for decades. Writer Micheal Lewis realized another investment game was being played out in baseball, notably by the A's. He gained inside access to A's general manager Billy Beane and got a look at how Beane's value players differently than other teams. In 2003, he wrote a book called Moneyball: The Art of Winning an Unfair Game

The Oakland organization assesses offensive production differently than others, stressing on-base percentage and power, de-emphasizing stolen bases and putting the ball in play. It has engendered an approach to acquiring talent based as much on statistical achievement as on traditional tools, an approach that has gripped some franchises and galled many traditionalists.

With the Pro Basketball Forecast, John Hollinger takes an in-depth and insightful look at the game. Downplayed are all the per-game statistics; in their place are points, rebounds, and assists per forty minutes. Hollinger also examines how many possessions each player uses and what percentage of his team's rebounds he collects.

The method that gives an expected winning percentage using the ratio of a team's wins and losses is related to the number of points scored and allowed.

Expected Winning Percentage Formula=(Points Scored)^16.5/[Points Scored)^16.5 + (Points Allowed)^16.5)]
