"The objective of this book is to lay the foundation for shrinkage-type estimators and to compare statistical properties of penalty and non penalty estimation strategies for some popular linear models. ... Undoubtedly this volume will serve as an excellent textbook for advanced undergraduate and graduate courses involving penalty and non penalty estimation and as a references source for professional statisticians and practitioners." (Vyacheslav Lyubchich, Technometrics, Vol. 57 (1), February, 2015) "The book's goal is to present some shrinkage, penalty and pretest estimation techniques for different models (e.g., normal, Poisson, multiple regression, etc.). Selected penalty estimation techniques are compared with the full model, sub-model, pretest, and shrinkage estimators in the regression case. The book is dedicated to graduate students, researchers and practitioners in this field." (Marina Gorunescu, zbMATH 1306.62002, 2015) "This book is a comprehensive and well-illustrated overview of the developments in this area in the last decade. ... the book is a very good source for those who want to start research in the area of preliminary test and Stein-type estimation in the direction of penalty estimation using a priori information. It will also be of interest and immense help to those interested in the theoretical as well as applied aspects of pretesting, shrinkage and penalty estimation."
