Learn data science by doing data science! Data Science Using Python and R will get you plugged into the world’s two most widespread open-source platforms for data science: Python and R. Data science is hot. Bloomberg called data scientist “the hottest job in America.” Python and R are the top two open-source data science tools in the world. In Data Science Using Python and R, you will learn step-by-step how to produce hands-on solutions to real-world business problems, using state-of-the-art techniques. Data Science Using Python and R is written for the general reader with no previous analytics or programming experience. An entire chapter is dedicated to learning the basics of Python and R. Then, each chapter presents step-by-step instructions and walkthroughs for solving data science problems using Python and R. Those with analytics experience will appreciate having a one-stop shop for learning how to do data science using Python and R. Topics covered include data preparation, exploratory data analysis, preparing to model the data, decision trees, model evaluation, misclassification costs, na?ve Bayes classification, neural networks, clustering, regression modeling, dimension reduction, and association rules mining. Further, exciting new topics such as random forests and general linear models are also included. The book emphasizes data-driven error costs to enhance profitability, which avoids the common pitfalls that may cost a company millions of dollars. Data Science Using Python and R provides exercises at the end of every chapter, totaling over 500 exercises in the book. Readers will therefore have plenty of opportunity to test their newfound data science skills and expertise. In the Hands-on Analysis exercises, readers are challenged to solve interesting business problems using real-world data sets. 通過(guò)數(shù)據(jù)科學(xué)學(xué)習(xí)數(shù)據(jù)科學(xué)！ 數(shù)據(jù)科學(xué)使用Python和R將使您進(jìn)入世界上兩個(gè)最廣泛的數(shù)據(jù)科學(xué)開源平臺(tái)：Python和R. 數(shù)據(jù)科學(xué)很熱門。 Bloomberg稱數(shù)據(jù)科學(xué)家是“美國(guó)最熱門的工作。”Python和R是世界上最暢銷的兩個(gè)開源數(shù)據(jù)科學(xué)工具。在使用Python和R的數(shù)據(jù)科學(xué)中，您將逐步學(xué)習(xí)如何使用最先進(jìn)的技術(shù)為現(xiàn)實(shí)世界
