Robust Methods for Data Reduction gives a non-technical overview of robust data reduction techniques, encouraging the use of these important and useful methods in practical applications. The main areas covered include principal components analysis, sparse principal component analysis, canonical correlation analysis, factor analysis, clustering, double clustering, and discriminant analysis.

The first part of the book illustrates how dimension reduction techniques synthesize available information by reducing the dimensionality of the data. The second part focuses on cluster and discriminant analysis. The authors explain how to perform sample reduction by finding groups in the data.

Despite considerable theoretical achievements, robust methods are not often used in practice. This book fills the gap between theoretical robust techniques and the analysis of real data sets in the area of data reduction. Using real examples, the authors show how to implement the procedures in R. The code and data for the examples are available on the book's CRC Press web page.

Reviews

"... this book tries to avoid technicalities and focuses on illustrating the power of robust techniques in action. Additionally, it covers some novel techniques, involving data reduction ... An important concept addressed in Part 2 of the book is independent cell-wise contamination. A large number of variables and a relatively small number of cases are commonplace in modern statistical applications. ... The proposed snipping methodology is tailored to be applied in the presence of cell-wise contamination, and from my point of view, is one of the principal methodological contributions of the book. ...
In summary, this book is interesting and useful. The book is not an attempt to systematically review all the literature in robust data reduction. However, it proposes a selection of techniques that are simple to understand or to use in practice."

"'Robust Methods for Data Reduction' makes it easy for practitioners of big-data analytics to conduct robust and efficient data reduction. It is a timely topic in which recently prescribed algorithms and methodological research findings are properly assimilated and presented in a lucid fashion. The book serves as a good introductory book that motivates and teaches the art of developing robust frameworks for synthesis and reduction of large, complex datasets...The most appealing aspect of this book is that all of the concepts and algorithms described are inspired by real-data examples. All of the methods presented in this book are accompanied by extensive codes and exhaustive documentation on how to implement them in the R computing environment. Readers can download the data and the computer code used in the book from the publisher's webpage...The collection of data examples and the pedagogical writing style make it an ideal text for instructors aiming to quickly train students on proper data-reduction techniques...This book will be particularly useful for courses with R labs. It is bound to find a wide and enduring readership and will be a valuable addition to the library of any data scientist."
