Introduction To Data Science

Rafael A. Irizarry CRC Press

Introduction to Data Science: Data Analysis and Prediction Algorithms with R introduces concepts and skills that can help you tackle real-world data analysis challenges. It covers concepts from probability, statistical inference, linear regression, and machine learning. It also helps you develop skills such as R programming, data wrangling, data visualization, predictive algorithm building, file organization with UNIX/Linux shell, version control with Git and GitHub, and reproducible document preparation. This book is a textbook for a first course in data science. No previous knowledge of R is necessary, although some experience with programming may be helpful. The book is divided into six parts: R, data visualization, statistics with R, data wrangling, machine learning, and productivity tools. Each part has several chapters meant to be presented as one lecture. The author uses motivating case studies that realistically mimic a data scientist’s experience. He starts by asking specific questions and answers these through data analysis so concepts are learned as a means to answering the questions. Examples of the case studies included are: US murder rates by state, self-reported student heights, trends in world health and economics, the impact of vaccines on infectious disease rates, the financial crisis of 2007-2008, election forecasting, building a baseball team, image processing of hand-written digits, and movie recommendation systems. The statistical concepts used to answer the case study questions are only briefly introduced, so complementing with a probability and statistics textbook is highly recommended for in-depth understanding of these concepts. If you read and understand the chapters and complete the exercises, you will be prepared to learn the more advanced concepts and skills needed to become an expert.

How We Read Now

Naomi S. Baron Oxford University Press, USA

"The digital revolution has transformed reading. Onscreen text, audiobooks, podcasts, and videos often replace print. We make these swaps for pleasure reading, but also in schools. How We Read Now is a ringside seat to the impact of reading medium on learning. Teachers, administrators, librarians, and policymakers need to make decisions about classroom materials. College students must weigh their options. And parents face choices for their children. Digital selections are often based on cost or convenience, not educational evidence. Current research offers essential findings about how print and digital reading compare when the aim is learning. Yet the gap between what scholars and the larger public know is huge. How We Read Now closes the gap. The book begins by sizing up the state of reading today, revealing how little reading students have been doing. The heart of the book connects research insights to practical applications. Baron draws on work from international researchers, along with results from her collaborative studies of student reading practices ranging from middle school through college. The result is an impartial view of the evidence, including where the jury is still out. The book closes with two challenges. The first is that students increasingly complain print is boring. And second, for all the educational buzz about teaching critical thinking, digital reading is inherently ill-suited for cultivating these habits of mind. Since screens and audio are now entrenched - and valuable - platforms for reading, we need to rethink how to help learners use them wisely"--

A Million Random Digits With 100 000 Normal Deviates

Minnesota Historical Society

Not long after research began at RAND in 1946, the need arose for random numbers that could be used to solve problems of various kinds of experimental probability procedures. These applications, called Monte Carlo methods, required a large supply of random digits and normal deviates of high quality, and the tables presented here were produced to meet those requirements.This book was a product of RAND's pioneering work in computing, as well a testament to the patience and persistence of researchers in the early days of RAND. The tables of random numbers in this book have become a standard reference in engineering and econometrics textbooks and have been widely used in gaming and simulations that employ Monte Carlo trials. Still the largest published source of random digits and normal deviates, the work is routinely used by statisticians, physicists, polltakers, market analysts, lottery administrators, and quality control engineers. A 2001 article in the New York Times on the value of randomness featured the original edition of the book, published in 1955 by the Free Press. The rights have since reverted to RAND, and in this digital age, we thought it appropriate to reissue a new edition of the book in its original format, with a new foreword by Michael D. Rich, RAND's Executive Vice President
