Review Quotes: "Overall, the book complements existing books on nonparametric density estimation with its focus on multivariate data, visualization and sieve-type estimators." (Mathematical Reviews, 2011)
"The book is suitable for courses in data analysis, multivariate analysis, and nonparametric statistics at the upper-undergraduate and graduate levels. Since it combines mathematical analysis with practical implementation it is also recommended to practitioners and researchers in the fields of statistics, computer science, economics and engineering." (Zentralblatt MATH, 2011)
