Wassily Hoeffding's research papers are among the most cited in the statistical literature. This volume gathers together Hoeffding's published papers and reviews, including specially commissioned English translations of three major early research papers originally published in German. It also contains three essays assessing the impact of Hoeffding's work in various areas including Nonparametric Statistics, Sequential Analysis, Probability Inequalities and Large Deviation Theory. This unique collection should be an invaluable resource for researchers and graduate students. The translated papers add further to its value as a historical reference volume. "Wassily Hoeffding was one of the giants in the development of the field of statistics. His work was path-breaking and deep, he pursued it with tenacity, and demanded the highest standards of himself." Norman Johnson
