Описание книги

Sports Analytics in Practice with R A practical guide for those looking to employ the latest and leading analytical software in sport In the last twenty years, sports organizations have become a data-driven business. Before this, most decisions in sports were qualitatively driven by subject-matter experts. In the years since numerous teams found success with “Money Ball” analytical perspectives, the industry has sought to advance its analytical acumen to improve on- and off-field outcomes. The increasing demand for data to inform decisions for coaches, scouts, and players before and during sporting events has led to intriguing efforts to build upon this quantitative approach. As this methodology for assessing performance has matured and grown in importance, so too has the open-source R software emerged as one of the leading analytical software packages. In fact, R is a top 10 programming language that is useful in academia and industry for statistics, machine learning, and rapid prototyping. Sports Analytics in Practice with R neatly marries these two advances to teach basic analytics for sports-related use—from cricket to baseball, from basketball to tennis, from soccer to sports gambling, and more. Sports Analytics in Practice with R readers will also find: A broad perspective of sports, focusing on a wide range of sports rather than just one The first book of its kind that features coding examples Case study approach throughout the book Companion website including data sets to work through alongside the explanations Sports Analytics in Practice with R is a helpful tool for students and professionals in the sports management field, but also for sports enthusiasts who have a coding background.

Отрывок из книги

This book has been a long journey in the making. Originally the book’s scope was centered on individualized chapters demonstrating analytical techniques within a sports context. The goal is that a reader inherits various tools that act as a foundation for analysis to build upon and add complexity with subsequent analyses as the reader’s technical acumen and sports interests grow. Each chapter is meant to be a standalone reference as the reader explores and learns. This also frees up the reader to focus on topics of interest. For example, a reader may not want to learn about natural language processing so could skip that chapter altogether to focus on another subject such as optimizing a fantasy football lineup. The book’s undertaking grew in complexity due to a personal commitment to demonstrate concepts on diverse data sets including Paralympic athletes, female soccer and basketball, and less US-centric popular sports including cricket in addition to the more typically demonstrated sports analyses of men’s football, baseball, and basketball. My goal is to make the subject accessible and relevant to many in the analytics field despite this effort slowing the book’s creation. Keep in mind a chapter’s concepts can be applied to many sports domains. For example, the text analysis applied to cricket fan forum posts can easily be applied to men’s basketball fan tweets or forum posts. Each chapter’s takeaway is meant to be a broadly useful tool, not a brittle or narrowly focused analysis. Additionally, the book was delayed due to the pandemic’s effect on the sports-world. Admittedly the shortened seasons, canceled games, and other changes that created outlier statistics pales in comparison to the pandemic’s hardship and humanistic impact outside of sports. Despite these challenges, the book’s end result was worth the delay. The final product covers many diverse concepts, and data, encouraging analytics professionals to enjoy the intersection of sports and analysis.

Indexing also works for entire columns or entire rows. This is done by leaving the rows position blank or the columns position blank on either side of the comma. To call the second column of the data frame simply use single brackets, nothing on the left of the comma and a 2 to the right of the comma as shown.
