Oreilly - Practical Data Science with R Video Edition
by Nina Zumel, John Mount | Released March 2014 | ISBN: None


"A unique and important addition to any data scientist's library." Jim Porzak, Cofounder Bay Area R Users Group Practical Data Science with R lives up to its name. It explains basic principles without the theoretical mumbo-jumbo and jumps right to the real use cases you'll face as you collect, curate, and analyze the data crucial to the success of your business. It shows you how to design experiments (such as A/B tests), build predictive models, and present results to audiences of all levels. You'll apply the R programming language and statistical analysis techniques to carefully explained examples based in marketing, business intelligence, and decision support. Business analysts and developers are increasingly collecting, curating, analyzing, and reporting on crucial business data. The R language and its associated tools provide a straightforward way to tackle day-to-day data science tasks without a lot of academic theory or advanced mathematics. Inside: Data science for the business professional Statistical analysis using the R language Project lifecycle, from planning to delivery Numerous instantly familiar use cases Keys to effective data presentations This book is accessible to readers without a background in data science. Some familiarity with basic statistics, R, or another scripting language is assumed. Nina Zumel and John Mount are cofounders of a San Francisco-based data science consulting firm. Both hold PhDs from Carnegie Mellon and blog on statistics, probability, and computer science at win-vector.com. Covers the process end-to-end, from data exploration to modeling to delivering the results. Nezih Yigitbasi, Intel Full of useful gems for both aspiring and experienced data scientists. Fred Rahmanian, Siemens Healthcare Hands-on data analysis with real-world examples. Highly recommended. Dr. Kostas Passadis, IPTO NARRATED BY JOSEF GAGNIER Show and hide more
