  • Chapter Two Massey’S Method
    Chapter Two Massey’s Method The Bowl Championship Series (BCS) is a rating system for NCAA college football that wasdesignedtodeterminewhichteamsareinvitedtoplayinwhichbowlgames.The BCS has become famous, and perhaps notorious, for the ratings it generates for each team in the NCAA. These ratings are assembled from two sources, humans and computers. Human input comes from the opinions of coaches and media. Computer input comes from six computer and mathematical models—details are given in the aside on page 17. The BCS ratings for the 2001 and 2003 seasons are known as particularly controversial among sports fans and analysts. The flaws in the BCS selection system as opposed to a tournament playoff are familiar to most, including the President of the United States—read the aside on page 19. Initial Massey Rating Method In 1997, Kenneth Massey, then an undergraduate at Bluefield College, created a method for ranking college football teams. He wrote about this method, which uses the mathematical theory of least squares, as his honors thesis [52]. In this book we refer to this as the Massey method, despite the fact that there are actually several other methods attributed to Ken Massey. Massey has since become a mathematics professor at Carson-Newman College and today continues to refine his sports ranking models. Professor Massey has created various rat- ing methods, one of which is used by the Bowl Championship Series K. Massey (or BCS) system to select NCAA football bowl matchups—see the aside on page 17. The Colley method, described in the next chapter, is also one of the six computer rating sys- tems used by the BCS.

Abstract: Statistical analysis combined with data mining and machine learning is increasingly used in sports. This paper presents an overview of existing commercial information systems used in game analysis and describes the new and improved version of originally developed data-driven Web application / information system called Basketball Coach Assistant (later BCA) for sports statistics and analysis. The aim of BCA is to provide the essential information for decision making in training process and coaching basketball teams. Special emphasis, along with statistical analysis, is given to the player’s progress indicators and statistical analysis based on data mining methods used to define played game point’s difference classes. The results obtained by using BCA information system, presented in tables, proved to be useful in programing training process and making strategic, tactical and operational decisions. Finally, guidelines for the further information system development are given primarily for the use of data mining and machine learning methods. 1 INTRODUCTION information for decision making in training process and coaching basketball teams.

  • Ranking the Greatest NBA Players: an Analytics Analysis
    1 Ranking the Greatest NBA Players: An Analytics Analysis An Honors Thesis by Jeremy Mertz Thesis Advisor Dr. Lawrence Judge Ball State University Muncie, Indiana July 2015 Expected Date of Graduation May 2015 1-' ,II L II/du, t,- i II/em' /.. 2 ?t; q ·7t./ 2 (11 S Ranking the Greatest NBA Players: An Analytics Analysis . Iv/If 7 Abstract The purpose of this investigation was to present a statistical model to help rank top National Basketball Association (NBA) players of all time. As the sport of basketball evolves, the debate on who is the greatest player of all-time in the NBA never seems to reach consensus. This ongoing debate can sometimes become emotional and personal, leading to arguments and in extreme cases resulting in violence and subsequent arrest. Creating a statistical model to rank players may also help coaches determine important variables for player development and aid in future approaches to the game via key data-driven performance indicators. However, computing this type of model is extremely difficult due to the many individual player statistics and achievements to consider, as well as the impact of changes to the game over time on individual player performance analysis. This study used linear regression to create an accurate model for the top 150 player rankings. The variables computed included: points per game, rebounds per game, assists per game, win shares per 48 minutes, and number ofNBA championships won. The results revealed that points per game, rebounds per game, assists per game, and NBA championships were all necessary for an accurate model and win shares per 48 minutes were not significant.

  • Predicting Outcomes of NCAA Basketball Tournament Games
    Cripe 1 Predicting Outcomes of NCAA Basketball Tournament Games Aaron Cripe March 12, 2008 Math Senior Project Cripe 2 Introduction All my life I have really enjoyed watching college basketball. When I was younger my favorite month of the year was March, solely because of the fact that the NCAA Division I Basketball Tournament took place in March. I would look forward to filling out a bracket every year to see how well I could predict the winning teams. I quickly realized that I was not an expert on predicting the results of the tournament games. Then I started wondering if anyone was really an expert in terms of predicting the results of the tournament games. For my project I decided to find out, or at least compare some of the top rating systems and see which one is most accurate in predicting the winner of the each game in the Men’s Basketball Division I Tournament. For my project I compared five rating systems (Massey, Pomeroy, Sagarin, RPI) with the actual tournament seedings. I compared these systems by looking at the pre-tournament ratings and the tournament results for 2004 through 2007. The goal of my project was to determine which, if any, of these systems is the best predictor of the winning team in the tournament games. Project Goals Each system that I compared gave a rating to every team in the tournament. For my project I looked at each game and then compared the two team’s ratings. In most cases the two teams had a different rating; however there were a couple of games where the two teams had the same rating which I will address later.

  • Basketball - Wikipedia, the Free Encyclopedia
    Basketball - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Basketball Basketball From Wikipedia, the free encyclopedia Basketball is a sport played by two teams of five players on a rectangular court. The objective is to shoot a ball through a Basketball hoop 18 inches (46 cm) in diameter and 10 feet (3.048 m) high mounted to a backboard at each end. Basketball is one of the world's most popular and widely viewed sports.[1] A team can score a field goal by shooting the ball through the basket during regular play. A field goal scores three points for the shooting team if the player shoots from behind the three-point line, and two points if shot from in front of the line. A team can also score via free throws, which are worth one point, after the other team was assessed with certain fouls. The team with the most points at the end of the game wins, but additional time (overtime) is issued when the score is tied at the end of regulation. The ball can be advanced on the court by bouncing it while walking or running or throwing it to a teammate. It is a violation to lift or drag one's pivot foot without dribbling the ball, to carry it, or to hold the ball with both hands then resume dribbling. Michael Jordan goes for a slam dunk at the old Boston Garden As well as many techniques for shooting, passing, dribbling Highest FIBA and rebounding, basketball teams generally have player governing body positions and offensive and defensive structures (player positioning).

Jay Coleman Department of Management, Marketing, and Logistics, Coggin College of Business, University of North Florida, 4567 St. Johns Bluff Road, South, Jacksonville, Florida 32224-2645, [email protected] One metric used to evaluate the myriad ranking systems in college football is retrodictive accuracy. Maximizing retrodictive accuracy is equivalent to minimizing game score violations: the number of times a past game’s winner is ranked behind its loser. None of the roughly 100 current ranking systems achieves this objective. Using a model for minimizing violations that exploits problem characteristics found in college football, I found that all previous ranking systems generated violations that were at least 38 percent higher than the minimum.

  • An Investigation of the Relationship Between Junior Girl’S Golf Ratings and Ncaa Division I Women’S Golf Ratings
    AN INVESTIGATION OF THE RELATIONSHIP BETWEEN JUNIOR GIRL’S GOLF RATINGS AND NCAA DIVISION I WOMEN’S GOLF RATINGS Patricia Lyn Earley A thesis submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Master of Arts in the Department of Exercise and Sport Science (Sport Administration). Chapel Hill 2011 Approved By: Edgar W. Shields, Jr., Ph.D. Barbara Osborne, Esq. Deborah L. Stroman, Ph.D. ABSTRACT PATRICIA LYN EARLEY: An Investigation of the Relationship Between Junior Girl’s Golf Ratings and NCAA Division I Women’s Golf Ratings (Under the direction of Edgar W. Shields, Jr., Ph.D.) Coaches often depend on rating systems to determine who to recruit. But how reliable are these ratings? Do they help coaches find a player that will contribute to the team’s success? This research examined the degree of importance that should be placed on junior golf ratings and if these ratings will help college coaches predict the impact of each recruit. The research sought to discover the relationship between 207 subjects’ junior golf ratings (Golfweek/Sagarin Junior Girls Golf Ratings) and their freshman, sophomore, junior and senior year golf ratings (NCAA Division I Women’s College Golf Ratings), rate of improvement and number of starter years using simple regression. A significant relationship was found between junior golf ratings and the freshman, sophomore, junior and senior year NCAA Division I women’s college golf ratings. A significant relationship was found between junior golf ratings and starter years but not with the rate of improvement.
