Modern Applied Statistics with S Fourth Edition 内容简介
S is a powerful environment for the statistical and graphical analysis of data. It provides the tools to implement many statistical ideas that have been made possible by the widespread availability of workstations having good graphics and computational capabilities. This book is a guide to using S environments to perform statistical analyses and provides both an introduction to the use of S and a course in modern statistical methods. Implementations of S are available commercially in S-PLUS®; and as the Open Source R for a wide range of computer systems.
The aim of this book is to show how to use S as a powerful and graphical data analysis system. Readers are assumed to have a basic grounding in statistics, and so the book is intended for would-be users of S-PLUS or R and both students and researchers using statistics. Throughout, the emphasis is on presenting practical problems and full analyses of real data sets. Many of the methods discussed are state of the art approaches to topics such as linear, nonlinear and smooth regression models, tree-based methods, multivariate analysis, pattern recognition, survival analysis, time series and spatial statistics. Throughout modern techniques such as robust methods, non-parametric smoothing and bootstrapping are used where appropriate.
This fourth edition is intended for users of S-PLUS 6.0 or R 1.5.0 (or later). A substantial change from the third edition is updating for the current versions of S-PLUS and adding coverage of R. The introductory material has been rewritten to emphasis the import, export and manipulation of data. Increased computational power allows even more computer-intensive methods to be used, and methods such as GLMMs, MARS, Kohonen's SOM and support vector machines are considered.
The authors have written several software libraries that enhance S-PLUS and R; these and all the datasets used are supplied with Windows versions of S-PLUS and all versions of R, and are also available on the Internet in versions for Windows and Unix. There are extensive on-line complements covering advanced material, exercises and new features of S-PLUS and R as they are introduced.
Dr Venables is a Senior Statistician with the CSIRO in Australia. He has given many courses on statistical computing, data analysis and graphics using S in Australia, Europe and the USA. Professor Ripley holds the Chair of Applied Statistics at the University of Oxford, and is the author of four other books on spatial statistics, simulation, pattern recognition and neural networks. They are the joint authors of `S Programming', the authoritative guide to using the S language.
Modern Applied Statistics with S Fourth Edition 精彩文摘
Statistics is fundamentally concerned with the understanding of structure in data.One of the effects of the information-technology era has been to make it much easier to collect extensivedatasets with minimal humanintervention. Fortunately,the same technological advances allow the users of statistics access to much more powerful ‘calculators’ to manipulate and display data. This book is about the modern developments in applied statistics that have been made possible by the widespread availability of workstations with high-resolution graphics and ample computational power. Workstations need software, and the S 1 system developed at Bell Laboratories (Lucent Technologies, formerly AT&T) provides a very flex-ible and powerful environment in which to implement new statistical ideas. Lu-cent’s current implementation of S is exclusively licensed to the Insightful Cor-poration 2 , which distributes an enhanced system called S-PLUS.
