This book provides an excellent treatment of the intricacies and applications of Nonparametric Statistics. After a fairly detailed study of the fundamentals of mathematical statistics, order statistics, one sample problems, two-sample problems and k-sample problems are covered in a most comprehensive and pedagogical way. In particular, excellent treatments are given of the Jackknife Method as well as of Kolmogorov-Smirnov Tests. A highly recommended book. It is undoubtedly one of the best sources of information on the subject (both mathematically and applied) in a most direct way.
