Summary
Summary
Suitable for a compact course or self-study, Computational Statistics: An Introduction to R illustrates how to use the freely available R software package for data analysis, statistical programming, and graphics. Integrating R code and examples throughout, the text only requires basic knowledge of statistics and computing.
This introduction covers one-sample analysis and distribution diagnostics, regression, two-sample problems and comparison of distributions, and multivariate analysis. It uses a range of examples to demonstrate how R can be employed to tackle statistical problems. In addition, the handy appendix includes a collection of R language elements and functions, serving as a quick reference and starting point to access the rich information that comes bundled with R.
Accessible to a broad audience, this book explores key topics in data analysis, regression, statistical distributions, and multivariate statistics. Full of examples and with a color insert, it helps readers become familiar with R.

Choice Review
This book provides an introduction to the free programming language and software system R, which is widely used for statistical applications. In the introduction, Sawitzki (StatLab, Heidelberg, Germany) mentions that the work is for users who have some background knowledge of statistics, including such concepts as distribution functions, mean, and variance, and some knowledge of classical distributions, e.g., binomial, normal, etc. The volume consists of four parts: "Basic Data Analysis," "Regression," "Comparisons" (of treatments/distributions), and "Dimensions 1, 2, 3, ..., (infinity)" (analysis of multivariate data). A special feature of the book is each section's concluding, one-page summary of its contents. The author provides a solid introduction to R, and discusses a variety of uses of R for statistical analysis, with an abundance of examples showing how to use the language. Computational Statistics definitely deserves to be in the library of all institutions where R is used or taught. Summing Up: Highly recommended. All collections. R.
