This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Baseball has long provided statisticians a playground for analysis. In this report we discuss the history of Major League Baseball (MLB) umpires, MLB data collection, and the use of technology in sports officiating. We use PITCHf/x data to answer 3 questions. 1) Has the proportion of incorrect calls made by a major league umpire decreased over time? 2) Does the proportion of incorrect calls differ for umpires hired prior to the implementation of technology in evaluating umpire performance from those hired after? 3) Does the rate of change in the proportion of incorrect calls differ for umpires hired prior to the implementation of technology in evaluating umpire performance from those hired after? PITCHf/x is a publicly available database which gathers characteristics for every pitch thrown in one of the 30 MLB parks. In 2002, MLB began to use camera technology in umpire evaluations; prior to 2007, the data were not publicly available. Data were collected at the pitch level and the proportion of incorrect calls was calculated for each umpire for the first third, second third, and last third of each of the seasons for 2008-2011. We collected data from retrosheet.org, which provides game summary information. We also determined the year of each umpire's MLB debut to differentiate pre- and post-technology hired umpires for our analysis. We answered our questions of interest using longitudinal data analysis, using a random coefficients model. We investigated the choice of covariance structure for our random coefficients model using Akaike's Information Criterion and the Bayesian Information Criterion. Further, we compared our random coefficients model to a fixed slopes model and a general linear model.
Book Synopsis Data Analytics in Football by : Daniel Memmert
Download or read book Data Analytics in Football written by Daniel Memmert and published by Routledge. This book was released on 2018-05-30 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data Analytics in Football provides students, researchers and coaches with a firm grounding in the principles of modern performance analysis. It offers an insight into the use of positional data, exploring how it can be collected, modelled, analysed and interpreted. Introducing cutting-edge methods, the book challenges long-held assumptions and encourages a new way of thinking about football analysis. Based on data collected from the German Bundesliga and the UEFA Champions League, the book seeks to define the role of positional data in football match analysis by exploring topics such as: What is positional data analysis and how did it emerge from conventional match analysis? How can positional data be collected and which technologies can be used? What are the benefits of a data-driven approach to decision making in football? What Key Performance Indicators based on positional data should be used? How can traditional match analysis be complemented by using positional data and advanced KPIs? How can these new methods evolve in the future? Accessibly written, packed full of examples from elite football and supplemented with expert interviews (Ralf Rangnick, Urs Siegenthaler and others), Data Analytics in Football is a thought-provoking, rigorously evidence-based guide to the use of data analytics in football performance analysis. As such, it is a vital resource for any student, researcher or coach interested in performance analysis and skill acquisition, or anyone interested in football more generally.

Book Synopsis The Science of Baseball by : A. Terry Bahill
Download or read book The Science of Baseball written by A. Terry Bahill and published by Springer. This book was released on 2018-12-04 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This augmented, new edition adds discussion of the bat’s vertical sweetness gradient, eye-hand cross-dominance, models for the swing of a bat, and accuracy of simulations. The book retains its description of dynamic collisions between baseballs, softballs, and bats, and the intricate modeling of these interactions, using only basic math and physical principles. Veteran baseball science author Terry Bahill explains models for the speed and spin of balls and bats and calculations for bat-ball collisions at a level accessible to most students of the science of baseball. Demystifying the most important factors for understanding bat performance—bat weight, moment of inertia, the coefficient of restitution, and characteristics of humans swinging the bats—Dr. Bahill also explains physical aspects of the optimal bat and the sweet spot. Praise for the First Edition “Dr. Bahill’s book is the perfect tool for teaching how to solve some of baseball’s basic science problems. Using only simple Newtonian principles and the conservation laws, Dr. Bahill explains how to model bat-ball collisions. Also, he derives equations governing the flight of the ball, and proceeds to show what factors affect air density and how this density affects the ball’s flight. And as a unique addition to his fine book, he provides advice for selecting the optimal bat—a surprising bonus!” Dave Baldwin, PhD Major League pitcher, 1966-1973, lifetime Major League ERA, 3.08 “If I were the General Manger of a baseball team, I would tell my people to write a ten-page paper describing what this book contains that could improve our performance. I think the book provides the foundation for change.” Bruce Gissing Executive VP-Operations (retired) Boeing Commercial Airplanes “[I] had a chance to read your research, and I fully agree with your findings.” Baseball Legend Ted Williams, in a 1984 letter to the author

Book Synopsis The Baseball Economist by : J.C. Bradbury
Download or read book The Baseball Economist written by J.C. Bradbury and published by Penguin. This book was released on 2008-02-26 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freakonomics meets Moneyball in this provocative exposé of baseball’s most fiercely debated controversies and some of its oldest, most dearly held myths. Providing far more than a mere collection of numbers, economics professor and popular blogger J.C. Bradbury shines the light of his economic thinking on baseball, exposing the power of tradeoffs, competition, and incentives. Utilizing his own “sabernomic” approach, Bradbury dissects baseball topics such as: • Did steroids have nothing to do with the recent homerun records? Incredibly, Bradbury’s research reveals steroids probably had little impact. • Which players are ridiculously overvalued? Bradbury lists all players by team with their revenue value to the team listed in dollars—including a dishonor role of those players with negative values—updated in paperback to include the 2007 season. • Does it help to lobby for balls and strikes? Statistics alone aren’t enough anymore. This is a refreshing, lucid, and powerful read for fans, fantasy buffs, and players—as well as coaches at all levels—who want to know what is really happening on the field.

Book excerpt: We’ve been tantalised by the idea of eternal youth since time immemorial. We’re always asking how we can live longer, and better. Or, to put it another way, why can’t we all be like Madame Calment who cycled till she was 100, smoked till she was 117 and died at the wonderfully old age of 122? Join veteran reporter Bill Gifford for a rip-roaring ride along the trail to the fountain of youth. Meet the scientists who have doubled the life-expectancy of mice by knocking out a single gene, and others like Aubrey de Grey, who claims that we are on the cusp of achieving ‘longevity escape velocity’, and who predicts that our children could live for a thousand years. An intoxicating mixture of deep reporting, fascinating science and sound advice, Spring Chicken will reveal the extraordinary breakthroughs that may yet bring us eternal youth, while exposing the dangerous deceptions that prey on the innocent and ignorant.

Book Synopsis Statistical Decision Theory by : James Berger
Download or read book Statistical Decision Theory written by James Berger and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision theory is generally taught in one of two very different ways. When of opti taught by theoretical statisticians, it tends to be presented as a set of mathematical techniques mality principles, together with a collection of various statistical procedures. When useful in establishing the optimality taught by applied decision theorists, it is usually a course in Bayesian analysis, showing how this one decision principle can be applied in various practical situations. The original goal I had in writing this book was to find some middle ground. I wanted a book which discussed the more theoretical ideas and techniques of decision theory, but in a manner that was constantly oriented towards solving statistical problems. In particular, it seemed crucial to include a discussion of when and why the various decision prin ciples should be used, and indeed why decision theory is needed at all. This original goal seemed indicated by my philosophical position at the time, which can best be described as basically neutral. I felt that no one approach to decision theory (or statistics) was clearly superior to the others, and so planned a rather low key and impartial presentation of the competing ideas. In the course of writing the book, however, I turned into a rabid Bayesian. There was no single cause for this conversion; just a gradual realization that things seemed to ultimately make sense only when looked at from the Bayesian viewpoint.
