Reviews / Votes
"This book seems suitable for an advanced undergraduate and/or introductory master's level course . . . Four appealing features of this book are its inclusion of an overview, a summary, exercises (with answers provided), and numerical examples for all sections." (American Mathematical Society, 1 November 2015)"The book is suitable for graduate and postgraduate students and researchers. This book is highly recommended." (Zentralblatt, 1 April 2015)
"This is an excellent and comprehensive presentation of the use of matrices for linear models. The writing is very clear, and the layout is excellent. It would serve well either as a class text or as the foundation for individual personal study." (International Statistical Review, 18 March 2014)
