A Hands-On Way to Learning Data AnalysisPart of the core of statistics, linear models are used to make predictions and explain the relationship between the response and the predictors. Understanding linear models is crucial to a broader competence in the practice of statistics. Linear Models with R, Third Edition explains how to use linear models in physical science, engineering, social science, and business applications. The book incorporates several improvements that reflect how the world of R has greatly expanded since the publication of the second edition.New to the Third Edition40% more content with more explanation and examples throughoutNew chapter on sampling featuring simulation-based methodsModel assessment methods discussedExplanation chapter expanded to include introductory ideas about causationModel interpretation in the presence of transformationCrossvalidation for model selectionChapter on regularization now includes the elastic netMore on multiple comparisons and the use of marginal meansDiscussion of design and powerLike its widely praised, best-selling predecessor, this edition combines statistics and R to seamlessly give a coherent exposition of the practice of linear modeling. The text offers up-to-date insight on essential data analysis topics, from estimation, inference, and prediction to missing data, factorial models, and block designs. Numerous examples illustrate how to apply the different methods using R.
